Laws can be changed. There’s no obligation to double down on them. We don’t keep lead pipes legal just because it’s very costly and time-intensive to replace all of them. That’s only an argument to start sooner rather than later. Guns would be a cakewalk to take off the streets compared to lead pipes. For one thing, guns need a consumable to function at all (ammunition).
Yes, car makers self-certify. You are not correct about that. Government crash tests aren’t a prerequisite to being allowed to sell a vehicle.

And then here we go with the carbrain argument “the only option is cars, America is set up for cars.” That was and continues to be an intentional choice. It is not irreversible. It is not something that we are forced to double down on just because that’s been our choice so far. Every time a road is built or a highway is widened that’s an intentional choice that is no less intentional or costly than sending the money toward transit options or pedestrian/cycling infrastructure.
The Netherlands had this exact same problem in the 70s and reversed it. Something like 90% of daily trips are under 5 miles, which is less than 30 minutes on a bike. The Netherlands has zero cities that are as populous as the top 10 most populous American cities.
“The bus adds significant time” but that’s the thing that people say who never take the bus. Can you work on your laptop while you drive? Can you read while you drive? I can do that on the bus. Sounds like I get time back, and my ride is statistically 10x safer.
Also, when it comes to large urban areas, you have to remember that most people live in them. That’s why they’re large urban areas. A New Yorker who never drives anywhere isn't someone who “doesn’t count” because they live in New York and it’s an anomaly. More of America depends on public transit than you think.
