Just look at that. This truck is taller than a used kid (10 years old). I assume the truck can run over pretty much any other age but probably the driver might be able to see older kid’s heads. Or we could teach our kids to jump to school rather than walk. If you see a truck, jump and make eye contact before jumping while crossing the street. Or we could tell our kids to never go outside until they are 21.
You know what would be a lot simpler and cheaper? Busses and trains and neighborhoods designed so that you can walk or bike to get basic necessities.
