Helmets with speakers (opinions on the dangers of listening to music while cycling)

if someone hits you and you're in a car, you'll be fine. not true on a bike.

i do listen to my ipod sometimes but it is definately more dangerous. i tend to look over my shoulders a lot more when i am..

Its true - you tend look a lot more.

It's a good idea not to rely on your hearing to guess what's coming up behind you. Usually you can hear the beautiful strains of a diesel engine as it overtakes you, although one of those electric vans flew past me the other day and I could hardly hear it.
