If you cycle you could get one of those face masks that people wear to stop the fumes. But arriving in the college smelling of fumes and sweat, covered in muddy water in the middle of January is not very appealing. You would either have to wear those lycra outfits (tres chic) and change at the college, then change to go home or stay all wet all day. Also, it is a pain cycling carrying a load of books etc, even in a backpack.
