I live next to a school, so there's a low speed limit (30 km/h). Still, people drive like race drivers and the city hasn't ever responded to the residents' hopes of introducing a speed camera.

I wanted to have some data on how many people speed, the max speed recorded, that sort of thing. Things the city should be doing after many complaints of dangerous driving and people being almost killed on zebra crossings.

I have a doorbell camera, and by analysing the footage using OpenCV and some code, I can track how fast people drive if you see how fast they move between two known points.

Average speed: 46 km/h :(

I'm starting to think about a similar thing for noise. The noise of motor vehicles seems to be out of control and I am sure it is causing misery for the majority of the population who have to live near roads. I reckon a single loud motorcycle could disturb tens of thousands of people, potentially waking or startling them, raising blood pressure etc. in a single 10 minute trip. Unfortunately I think awareness of this problem is even worse than speed.

What absolutely grinds my gears is when a loud motorcycle or sports car drives through my residential neighborhood right after patiently rocking my baby to sleep.

Interestingly, as a motorcycle and sports car owner myself, I never thought about that aspect for even a second until I became a dad—I drive much more gently nowadays (especially in residential neighborhoods)!

Right, because the car's cabin and motorcycle helmet protect the driver/rider from it. The noise they create are specifically designed to be heard by everyone but the operator. It's like me sitting in my back garden wearing earplugs, while blasting music out the front into the street.
