in some states it is against rules.
i sometimes drive barefoot too. my cousin always drive barefoot because she has a foot fetish. she finds barefoot driving erotic. once she drove her father' s truck to the beach and got stuck with it. i saw how she got excited as she tried to unstuck the poor truck barefoot. but she did it and made the truck unstuck again.
i think, barefoot driving is more comfy too. you really feel the pedals easier and also you do not live any dangers of slipping your heels or other kind of foot wears from the pedals. keep on driving barefoot and enjoy it ...

keep on barefoo, we can chat about it too. bye ...
