No reasonable amount of money would make up for it monetarily for me. I spend an extra 45 minutes a day riding instead of driving. If I worked those as overtime (I'm allowed to work as much OT as I want to) that would translate to about $25/day after taxes. So in rough terms it costs me about $500/month to commute by bike. Subtract off the $60/month I'd pay for gas, add $130/month for the cost of the car divided into 12 years (so far, and the car will go much longer), it's still costing me about $310 a month to commute by bike. OK, I wouldn't work that much overtime, but it definitely cuts into it by more than what it would cost me to drive even if I had to buy a new car every 10 years to do it.
