> I don't always signal because cars have this flaw where you need your hands on the steering wheel and you have to take it off to flick the signal switch.

I don't think I've ever taken my hand off the wheel just to use the turn signal. Is this just a product of hand size, or does your car have an unusual setup?

[edit] To clarify: I flick the turn signal lever with the my ring & middle fingers while keeping my palm against the wheel.
