I built a pair of bikes and sold a car. It was a summer, fair weather car, but I just didn’t use it any more, as I would rather be on the bicycle.

I use the bike for rides under 10 miles pretty consistently, and for trips up to 20mph.

Drawbacks:
Can’t carry other people.
Limited cargo carrying
Need a plan for rain.

Given my average speed on my car’s computer is about 34mph, and on the bike is 20mph, the bike only adds about 10 minutes to a 10 mile commute. And, that time can often be offset by dealing with parking.
