In a city. How about anyone living in the countyside? Do those people not exist? Where my parents live, there is are 3 buses per day. None around school time. How does a child get to school? Or should these families just move to the city?

Do families get to go anywhere for more than a few hours? How do you bring all their stuff along like clothes, toothbrush, etc. Every child needs a minimum of 1l of water all the time, and some snacks in case they get hungry. And toys. And change of clothes in case they spill the 1l of water on themselves in the winter.

What happens when both parents have 20kg+ bags and one of your children decides to run away, say into traffic?

Judging by the replies to my original comment, not many people on HN have children or have any idea what it involves.

While I instinctively agree with you, I have lots of friends with children who seem to do perfectly fine with just electric cargo bikes and public transport. And these are people with good jobs that could afford a big SUV if they really wanted one. So while you or I don't seem to get it, a lot of other people seem have worked it out no problem.

If your child runs in to traffic that's the exact moment you want the cars on the road to be small, light, and have short and low hoods so the drivers will see your child and stop before hitting them!

If your child decides to behave like a deer it won't matter if the cars are transparent, they're getting hit.

Even the new Chevy trucks that everyone loves to hate don't have a child blind spot that's larger than their stopping distance at any double digit speed.
