Also car height.
I've been hit by a car about 20 years ago and I kinda just rolled on top of it and landed behind confused with a few scrapes.
Getting hit by a car whose bumper is about shoulder height is much more likely to kill you.
Don’t worry! We’ll go through the process of revising safety ratings to include people outside the car just for auto manufacturers to switch their advertisements to say “five star passenger safety rating” instead 😀
If I'm being honest, I wouldn't let my (future) kids drive a little car. They'd save up enough money to get a shitty little car, and I'd pay the rest to get them a big car. I've seen what happens to little cars in crashes, and if people continue driving the way they do, I'd rather my kid be in a big car rather than a little one (not Western nation).
