Good point. The right hand is free to deal with (am I missing any?):
- radio, shifting, opening sunroof, window switch operation, adjusting mirror
- gesturing other drivers in threatening ways, texting, patting human/canine companions
- fist pumping when another car is pulled over for speeding instead of me
Some activities require both hands and steering with the thighs.
This is just a thought experiment that I do not condone nor practice:
- cleaning sunglasses, opening a chocolate bar, tying shoelaces
- playing the guitar, electric shaving, applying makeup
- filling a loan application to afford the Verrazano Bridge toll...
I've always thought the right side turn signal was a cool thing. The conversation might be better to ask what the logic was behind it. My guess is since most of the controls, along with the shifter, is used with the drivers right hand they put the signal stock on the right so you didn't have to change hands on the steering wheel. Even the window switches are on the center console.
