I didn't start because of a DUI but because my car and then my wife's car broke down within 4 months of eachother. We needed to buy her a new one and she wanted me to get a used one but the price in Philly for a used car w/100,000 plus miles on it is about $5000 or better. Ridiculous. So I decided to go car free, use public transportation and buy a bike. I'm lucky I'm only 4 miles from my place of business.
