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...
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.
They lose hours, lives, and a boatload of money every day in the current state. Removing the reliance on cars will improve those things.
