I want to let my kids walk wherever they want to. It’s great for them.

My 5 year old bikes to school, accompanied by an adult. It’s a bit more than half a mile away from the house.

I’d like to tell him he can do this on his own next year, but there’s a single intersection he has to cross that makes this difficult.

I’m not worried about him getting lost, abducted by a stranger or any host of movie plot scenarios. I’m worried about vehicles. Specifically pickup trucks and SUVs.

40 years ago a 5 or 6 year old mostly had to contend with sedans with hoods lower than 30 inches. Today there are large numbers of vehicles twice that high, where even an adult can’t look the driver in the eye at close distances.

The Insurance Institute for Highway Safety says:

  Vehicles with hood heights of more than 40 inches and blunt front ends angled at greater than 65 degrees were 44 percent more likely to cause fatalities.

I’ll probably let him bike alone anyway. But it’s a different equation because of the cars.

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.

As far as visibility is concerned, the only problems I've encountered in a big truck are to do with the driver-side A-pillar obscuring pedestrians about to cross the street on the other side of an intersection. It's the perfect width, and in just the right spot that I've had to stop in the middle of an intersection a few times now because I didn't see somebody as they just started to cross. I'm building the habit of moving my head around at intersections, but I'd spent decades before they changed regulations not having to do this (and it doesn't actually seem that big, but it really obscures a big chunk of arc, especially at "other side of the intersection" distances and greater).

In practice, if somebody is right in front of my grill where I can't see them, they were close enough for me to notice them before they got there without me having to be on high alert for people.

I'm not putting this here as a truck-vs-car thing or whatever, I'm just trying to people a realistic idea of where the blind spits are that actually cause trouble in my experience.

Thats the ubfortunate side effect of cafe standards. They have had to make what people want bigger each year to keep it exempted

I wonder why all these trucks (with the size, these are not cars) don't have forward-looking cameras mounted somewhere near headlights and feeding a screen on the dashboard, which would offer a "window" through the motor compartment. It should be trivially simple to produce, and most vehicles already have a screen for the camera on the back. Its presence would likely lower the insurance premium significantly, due to a much lower chance of hitting someone right ahead of the vehicle.
