I live in India, and here we drive on the left side of the road. Which means when I am cycling, I signal before turns with my right hand. Except when the road is very wet, I prefer to use the front brake since too much pressure on the rear brake makes the rear wheel slide around. I ride a road bike, and am yet to go OTB from hard braking - which could be partly because I instinctively stiffen my elbows and shift my weight backward during panic braking.
