Tried riding to work once...
It is truly amazing how, in the middle of nowhere, with a 4 lane limited access road, you still have drivers who are unwilling to move into the left lane to avoid hitting cyclists. Ir even just to give them room.
Needless to say, I do not ride to work due to how dangerous it would be.
Tell me, honestly, don't you think that there should be enough room to move over if you see a cyclist on this road?
