This is very dependent on the environment. I would not be so confident saying this about the USA in particular.

If you can stick to at least half-decent dedicated cycling infrastructure separated from cars, sure. If riding alongside traffic, I wouldn't be surprised that, depending on the exact route, the gains wouldn't outweigh the risks.

Generally speaking, operating a bike safely is considerably more difficult than a car and the margins of error are tiny.
