I love public transport. The idea of it. I will take a train or a metro happily but personally I'm not fond of busses. It's just me. Fortunately the nature of bus advertising in Copenhagen is such that I prefer to be on a bicycle behind or alongside the bus...
 

Perhaps bus companies should put these kinds of ads inside the busses in order to attract customers.

And reserve the space for adverts outside the busses for... peas and stuff.
