I didn't own a car (and very rarely borrowed or rented one) till I was in my 30s. With no car payments, no gas, no car taxes and fees and little in insurance, I saved a lot of money. (And spending that extra money on bike doodads, more bikes ...? Well that's just a matter of priorities and discipline. In those days I had the discipline. I had my workhorse fix gear commuter with fenders, a lock, LowRiders and front panniers and my good bike. For decades.
