that would be awesome. if only there was a way to monitor bikes and who runs them...
anyway, per hour is even more faulty than per kilometers.
nobody drives a bike for 5 hours straight, unless it's a professional competition.

I've never seen a car jumping on the sidewalk intentionally or running high speed among people in a park walking their kids in a stroller, in the almost 50 years I've been on this planet.
Plenty of people do, actually. When I was a bit more overweight and trying to lose it, I used to go for 4-6h long rides around London in the weekends, and 3-4h long rides in the evenings after work.
Lots of non-professional cyclists go on cycle tours where they can ride for 10h or more for several days.
On top of that, 1h-1h30min long rides to and from work and other places were quite common as they are for many cyclists, and I suspect this is about the same for drivers in big cities.
Comparing it per-kilometer is disingenuous due to the wildly different speed. If you want to make a fairer comparison, you should look at it per travel-hour. And cars definitely do all the things you mention bikes doing wrong - you are probably just so used to it that you don't notice it anymore.
