not sure if it under counted, when the smallest granularity is 0.5 cubic metres. Seems like it would balance out, some times higher sometimes lower.

0.5 cubic metres is 500 litres of water, that allows for a lot of variance each way.
so more accurate the better.

Will take awhile to generate revenue when considering the upfront cost of purchasing the metres, and installation costs.

Wind currents are down from the artic over western Canada. They pass east of the Rockies. Once far enough south (roughly Texas), they climb again. This time they travel along the mountain ranges of the Eastern USA.

They deposit over Eastern Ontario and Western Quebec.

So, we get American pollution, American NOx, COx and so on. That makes for acid rain.

Acid rain melts the bedrock. The melting yields Calcium Carbonate.. In water, it precipitates out and we call it scale.

A scientist some while ago by the name of Langelier did a great deal of work, and produced the Langelier index. It takes water parameters, such as hardness, alkalinity, ph. temperature and so on and produces an index.

It is a fairly straight forward calculation. It relies heavily on normalizing these parameters, so the LOG scale is used. An index of above 1, means the water is likely to scale, below 1 means the water is corrosive.

Ottawa water is above 1. And so scale hurts us. It clogs things.. And so delicate water meters clog and gunk up. Once that happens, they under report. And so it is not uncommon for a meter to be 1-10% below true reading.

The city probably pushes 1 M^3 per Ottawa resident, per Month. So a million M^3.. at the high end, the system may be registering 100,000 M^3 less. At the $5-$10 / M^3. The city is out 500K- 1 M... So, 600 K -12 M a year.... Peanuts!!!!

Now, you go to Edsel Ford and he approves a delivery charge hike... You see the city needs Edsel's permission to hike delivery charges.

Now the city adds $15 delivery charge.. at 300,000 Ottawa homes, 100,000 businesses.. you have 400,000 users at $15.. that is a cool $6 M a month, or 72 M a year.. Add to it the 600K to 12 M in water consumption. And you have added 73-84 M to city coffers.

Markie Mark was not born yesterday, Nor was Edsel, Nor are the 26 little dwarfs.

By the way, there is no cure for water if the Langelier index is above one, other than filtration and possibly and RO/DI system. Any of these options, can trip the water into having an index of -1 or lower. Making the water corrosive. So now, you need to have a sacrificial anode to treat the corrosive component. Either an easy to "dissolve metal", or an acid neutralizer, which is some form of a soft ceramic. I had a patent application, but left the company before it was finalized. I am not sure if it was ever awarded.

Old Markie Mark has a 140 M transit deficit. A city that is collapsing with no true industry/corporate base. The Feds have abandoned him. Edsel does not like us, we are Liberal. The city does not have a Pot to Piss in.

No road work, no maintenance, no nothing the last 10 years. Earlier this year they hired a company to go after old ticket holder. They were ruining people's credit rating. 5 K over the limit photo radar. Ticketing left right and center ( a bylaw officer must have nested on my street, my poor neighbours were eaten alive). Now the meter change..

Markie Mark and his 26 dwarfs have no money and are chasing ambulances to get any dime they can.

The next scheme is around the corner.. Pay toilets are next. We will be nickeled and dimed to death the next 2-5 years. .

I wonder what the numbers are on the age demographic of collisions caused. Is that data easily available? Young people need to mature as drivers, and that's one area I think they should be smacked down more and sooner with traffic violations be it pulled over or a camera ticket. Whenever I see someone going way too fast (not just a little over), speeding through a school zone, or most times I have a close call with someone obviously on their cell phone, they look like they're about 18 years old.

Can we look at data for unskilled drivers and how many accidents they cause, and also, what type of demographic they are?

I find more often than not, there is some completely clueless driver not knowing what to do...like stopped in the middle of traffic talking on their phone with the car off last week, and no hazard lights, for example. Caused 20 mins of traffic for no reason.

I'm more scared of an unskilled driver than I am of a young driver.

We need to make tests tougher, and make them mandatory every once in a while. Should have to complete an obstacle course in a certain amount of time without hitting any cones, to show you have skill. To show you can 3 point turn, or parallel park, of make a last second avoidance manoeuvre without taking a minute to do it and causing a huge traffic jam.

I'm all for regular re-testing. I would gladly do so. I know I'm not a perfect driver because no one is. Bad habits have a way of creeping in over time, and no one is infallible.

I hesitate to refer to personal experience, as I don't believe it's really representative of the average. That said, I could point to dozens of times this year alone where I have witnessed drivers of all stripes being utterly reckless, putting themselves and others in danger, whether it's on the highway, a collector, a traffic filled downtown street, or a quiet neighborhood side street.

Hell, I've almost been smoked 3 times as a pedestrian in a crosswalk in broad daylight this year alone. One wonderful lady who stopped less than a foot from my shins after turning left on a fresh green cried out she didn't see me there. In the middle of the god damned day.

For all the complaints about speed cameras and speed limits and blah blah blah, a polite reminder to the drivers in here that your impatience isn't worth risking someone else's health and wellbeing. You aren't perfect. You will make mistakes. And if you can't be bothered to be present while behind the wheel, then you should either be forced to relearn how to drive, or have the priveledge revoked entirely.

I have no problems with people mildy speeding provided they are skilled, and like you said, paying attention and present.

I find the speed limits are off (some are too high, some are too low) but generally, I would rather drive with people that go 10 or 20 over but are skilled, then people who drive under the speed limit but are horribly unskilled drivers.

Speed does kill, but unskilled drivers also kill, and then also piss off everyone on the road around them.

I will add clueless drivers to unskilled....like the ones who don't know you shouldn't just block a lane because you changed your mind, which I see people do all the time lol like "oh shit, wrong lane...let me just block this open lane until someone lets me in rather than going around and not blocking an open lane" which we often see downtown.


It's like 9/10 of the traffic jams I see aren't caused by an accident or by too many cars, but rather by one or two idiots doing something idiotic blocking a lane without realizing they're going to create some massive ripple affect traffic jam because they can't keep it flowing.

To your point, I think the most important thing a driver needs to understand and exhibit is how to be predictable.

Unskilled drivers are at least more predictable than nervous drivers, which are probably the worst of the bunch. Neither of those kinds of drivers should be on the road without additional training, IMO.

Regarding speeding, consider this: Stopping distances based on speed is not a linear increase, it's exponential.

So even a skilled driver going 10km/h over in a 50 km/h zone requires something like an extra 10 meters to come to a stop in dry road conditions, or 13 meters in wet road conditions. The average driver takes 1.5 seconds to react, and even at 50 km/h, that's around 20 meters of distance travelled before you hit the brakes. At 10 km/h over, that's 25 meters. At 20 km/h over, that's now almost 30 meters.

At 20 km/h over in a 50 zone, you're now at 21 meters and 28 meters of additional distance respectively before you come to a complete stop (total stop distance is 56m and 69m[nice]).

If the average person can run at 13 km/h, that's around 5 meters of distance travelled in that same 1.5 second reaction time to get out of the way of a driver.

In other words: Physics doesn't care about how skilled of a driver you are.

Reaction time would definitely be a part of the skill equation though...so you can't talk about reaction time and then say skill doesn't matter at the end.

Theres a video of a formula 1 drivers reaction time with I believe an NFL receiver where they're both trying to catch something that drops, and the F1 driver is so much quicker with his reaction. That's PART of the skill factor for sure. A skilled driver will also see the traffic ahead of the vehicle ahead of him start to brake and will be prepared. A skilled driver will also have checked all his mirrors and would know where to steer to avoid contact. These are all factors of what I'm talking about when I say skilled.

But what you mentioned about braking distance has me thinking as well...the type of car someone has makes a difference. If I see a gentleman in a Porsche speeding by 20, I'm less worried than a driver in a 2008 dodge ram speeding by 20.

I would wage that their braking distances at certain speeds are drastically different. Especially if the Porsche is maintained and the 16 year old ram isn't.

Here's a list of the top 100 cars by braking distance at 60mph (~95 km/h)

Top 100 quickest braking cars and bikes from 60 mph 2024 - FastestLaps.com

quickest braking cars and bikes from 60 mph

fastestlaps.com

How many of those do you see on the road at any given time?

Even within that top 100, the difference between first and last is around 45 feet at 95 km/h

F1 drivers are quite frankly a different breed. Their reaction times are near inhuman, given the typical spread of normal driver reaction times

1.5 second reaction time is an average of on-the-road drivers: there will be lower and higher reaction times. There is a lot of data available about F1 reaction times, but I think it's realistic to say they're around 1 second faster than the average person, if not faster.

Does the Porsche driver go through additional training to improve their reaction time? No. Do they have better brakes assuming regular maintenance? Of course.

Based on a consumer report from 2021, the average stop distances at 95 km/h for sports cars (best average results) is 120 feet, compared to 143 feet for large SUV's. Source: Cars, SUVs, and Trucks With the Best and Worst Braking Distances - Consumer Reports

Anyways, yes, skill is part of the equation, but only to a point. The rest is pure physics based on the car you're driving. And if the average is accurate, then 20 over isn't nearly as safe as some might want to think, and neither is 10 over.

For sure there are a lot of factors. I was pointing to the ones I care about more.


To me, something like 25-40 ft or whatever is quite the distance. It can be the difference between stopping 3 ft shy of hitting them, and smashing right through them at 20-30km/h and causing potential permanent injuries...

So of course performance of car matters.

And then reaction time being a skill matters too. 1 second at 100km/h is almost 92 ft travelled.

So having a reaction time closer to 1 than 2(taking your 1.5 average) can make the difference of 92 ft. Add in the superior car, and it can be a total of 120 ft or so...

Can be the difference between stopping no problem and causing a 5 car accident.

why would you convert 100km/h to ft per second? like, we have the metric system for a reason, damnit...

So if you start looking into distribution charts of perception reaction times, you'll see the lower bounds at around the .5 second mark, with upper thresholds ranging from 2-3 seconds.

How frequently does the person travelling at 100 km/h stopping have a faster perception reaction time than 1.5 seconds? As far as I can tell, it would be less frequent than someone exceeding the average.

For the sake of argument, lets use your example of someone travelling at 100 km/h in a high performance car with a higher than average perception reaction time. How do you factor in the people driving behind them? Do they also benefit from the same stopping ability and reaction times as the initial driver? While that initial driver may stop in time to prevent a 5 car accident, that doesn't mean the person behind them will.

In any event, we're still talking about non-insignificant distances, whether you're travelling at 50 km/h or 100+. While in some cases, improved car performance and perception reaction times may reduce the frequency of accidents, in other cases it becomes utterly irrelevant. To the pedestrian crossing the street, the difference between 1 and 1.5 second perceptive reaction times is still injury or death.
