This is true. Nor is the climate suitable everywhere, etc. However:
> riding a bicycle where there's cars on the road is a lot more dangerous than being in a car.
This is a problem that absolutely can solved by more "should". The police should police more, and the courts should be strict about endangering others with deadly weapons, even if those deadly weapons are on wheels.
> people are free to make their own choices.
People are "free" to speed, or to drive drunk, or to otherwise endanger others "where there's cars on the road". Looks like these "own choices" aren't a terribly good fit to many of the problems posed by cars.
