I personally feel that we have to give ourselves a bit more credit in regards to adapting to different controls and riding techniques. I have multiple vehicles with varied control methods. My '67 Mini is right hand drive, my scooter uses a brake lever on the left handle bar for rear brakes, and old british bike I once had was all backwards when it came to controls. Bicycles have the rear brake on the right handlebar and the front brake on the left. Heck going from a car to a motorcycle is completely different in itself! I MIGHT reach for the wrong lever or be confused for a quick second at the start (if I haven't driven or ridden the vehicle in a while) but after that, I have never felt unsafe or reacted poorly in an emergency situation because of control confusion.
