My commute is 3 minutes on my bike since I've moved 
I used to commute to the same job 3 different ways (times are each way):
- Bus - 45 mins
- Car - 25 mins
- Bike - 30 mins
I would never do the bus route again. Car was ok although the road sucked and was incredibly tedious. Bike was fine apart from the very windy/soggy days.
If I was to move jobs, my limits would probably be:
- Bus - never
- Car - 40 mins
- Bike - 30 mins
- Train - 45 mins (including getting to/from the station)
However, I'd want a massive salary jump if I were to need to commute, partly to cover the costs of transport, partly to cover the inconvenience.
