It's very non-uniform though. My 10-year-old car has 30k miles on it; at 40mpg and $3.50/gal gas, that's about $260/year on gas. That's because I lived 2 miles from work and biked in during the summer while I was at Google, and I've been working from home while I'm at my startup.
A lot of FANG employees pay nothing for transportation because they take the shuttle and don't have a car.
