We're offering our inexpert advice in all things automotive.
We might discuss your question on our podcast. Yes, this means that we've run out of ideas for episodes and are too lazy to do research.
Edit: Thanks for the questions everyone. We didn't have time to answer all of them on the show but I'll try to answer all of them on here. The episode probably won't be out for over a month since we've got a backlog of editing to do.
A lot of it depends on where you live, but I'd try taking lessons at a driving school. I took driving lessons at this school as a teenager, but there were also a few adults there at the time.
Depending on where you live, you also might be able to find a car-share subscription service like Zipcar where you can rent a car for a few hours at a time, which is usually cheaper than owning a car.
You could also get a scooter or e-bike, which would be much cheaper but also more dangerous.
