Cars/trucks do an extra special addition though: park in a lane because you're delivering something, or, ya know, doing something outside of the vehicle.

I've reported hundreds of cars parking in the bicycle lane this year alone..

Has anything happened from it?

Some news articles from me and other activists doing stuff has led to it becoming a higher priority in the department. So twice as many ticketed for it this year than earlier years in my city.

Still, the problem is that it's possible. Paint isn't infrastructure.

Do cars collide with people on sidewalks that frequently?

I was questioning the claim that cars hit people as frequently as scooters do on sidewalks. It seemed unlikely to me, but I don't live in a major city. I appreciate you taking the time to share links. I read each and they're sad stories, particularly the one involving a child that was hit by a vehicle pulling into a driveway. I think it's pretty undeniable that car accidents will be more fatal than electric scooters, but that was never really a question.
