I'm almost 2 meters tall and was crossing a street at a crosswalk with my bike yesterday, walking and pushing it at normal walking speeds, like the law requires. There was a car about to turn left from the lanes going left. There was a car from the lanes going right (the closest lanes to me) that slowed down as I started crossing the street. I assumed they saw me and that's why they were slowing down. Nope - they almost hit me but managed to hit the brakes very hard at the last possible second. Apparently they slowed down to make sure the car that would turn left would wait for them. If I was as tall as a 5 year old, maybe the car that almost hit me wouldn't have even seen me. If I got hit, I'd take it better than a 5 year old due to physics - my mass is bigger and the point where it would've hit me would've been my thighs instead of my torso. That car wasn't even with a tall hood or anything obstructing its view, just a regular car.

In another comment a few days ago I reminisced about how I was let running alone for hours on end when I was very young, and how that was normal.

It's a bit hard to reconcile both events now. I gained a lot of independence and had real unrestricted fun, but in hindsight I might've died a few times.

My idea, even if it might be traumatic, is to show the kid a few clips of people being hit by a car and getting mangled, with all the gore visible. Especially people following the laws and being careful. I miss /r/watchpeopledie as it was actually very educational.
