Do you put the kid in that seat?!?

When I was bike only I had my arm damaged in a way that it took close to a decade to get back to normal. On another occasion I was knocked unconscious. Both occasions were drivers who left turned into a parking lot without looking, crossing a lane then going right into me in the bike lane.
A car provides a nice cushion for those sorts of happening. I think if I had a child in either case there is a good chance they would be dead.
While I support the right of people to make their own risk assessments for their family, I fear it is only a matter of time until they come to understand what I did about Chicago biking.
I'm certainly not opposed. But my observation in the relatively nearby city when I go in and sit on the sidewalk at a restaurant is that the fairly new protected bike lanes have a fairly terrifying combination of transportation modes (bikes, ebikes, things that I guess are ebikes but look almost like small motorbikes, escooters, and pedestrians crossing). And then, because they're in a bike lane, many seem to assume the signal at the next street doesn't apply to them.
Not sure of the best answer.
Chicago has (recently?) put a lot of focus on their bike infrastructure (protected bike lanes, bike signals, bike only paths, etc) and it seems pretty widely used.
