true. i just mean that like usually when people need to "concentrate" they turn down the volume. riding a bike usually takes more concentration then driving a car. obviously, this isn't a blanket statement that is universally true. there are plennn-ty of idiots in cars and on bikes.
interesting thing about the rhythm when riding a bike, i think i recall reading on here awhile back a snippet of an article that stated something about not wanting to keep a rhythm? like timing your pedalstrokes to a beat, or something? i could be mistaken. anyhow.
i didnt mean to argue. i think that it does impair a rider more than a driver, though, simply because a rider sort of relies on sounds and sights moreso than a driver does.
a helmet? now that's just a huge, useless nuisance.
