The safest car is the one that is parked. I’m not anti-car but in terms of safety we should focus more on getting people using bus/rail/bike/walk especially for daily needs. It’s more cost effective too. Autonomous cars are cool and will be great for reducing crashes, but it’s an additive solution, not a subtractive one.
It’s okay to be anti-car. Even if you own a car and use it regularly. There’s more than enough reasons to be anti-car. Just pick your favorite.
Yes, instead of fixing the problem let's go back 100 years and start walking everywhere. It's easy for someone that works for home or an in office, but most people truly rely on their cars, otherwise they would lose hours everyday...
Public transit is not "100 years back". London, uk is not exactly backwards looking in that sense, and the vast majority of people use trains/metto to go to work.
I walk 10k steps a day on a normal day, only drive when necessary to go out of my normal routes. This has an added benefit of keeping me, an aging programmer, in shape (as well as other relevant activities).
Nothing dramatic about it at all.
Most people in societies built car-first/only (USA) truly rely on their cars. The situation is not the same in big parts of Europe and Asia. We can go 100 years forward and fund public infrastructure which is better for the environment, more safe and gives a much higher socio-economic value (except for the highway lobby).
It is healthy to walk. You should be walking probably an hour a day at least if we are being honest. You are made to hunt and forage all day, not sit down. Use it or lose it.
