I worked for a company (Genentech/Roche) until last year that would pay you $12.00/day for commuting on bike. They would also pay you to take their bus or to ride public transit or to ride in a car pool. The main reason for offering the incentive was they had reached the maximum number of parking spaces the city would allow for the site and the company was continuing to grow. They really had no where else for you to park. There were about 8000 regular employees at our campus plus an equal number of contracted staff. Genentech also gave us Jerseys/ Shorts/ Windbreakers/ water bottles/ Flat Kits etc ad nauseum. I quit because they stole my soul.
