Not really sure how well bikes would work where I live. The winters are harsh, and its steep hill after steep hill.

A valid concern. Bikes are good for fair weather and close proximity. Not all of the world is set up for this. Trains and busses have been around for a long time and can help reduce emissions and work in bad weather. Trains could require costly new infrastructure but busses can use existing roadways. The big goal should be to move away from cars. Ten people on a bus use less emissions then 10 cars on thier own.
