BEEP! BEEP! BEEP!
Basically, go slow and keep your eyes open. Look ahead at a distance of 1-2 seconds (not the 3-4 seconds you may be used to with higher speed traffic) and be ready to "flow" with the traffic around you instead of assuming that as long as you're driving within the rules that nothing bad will happen.
Be especially weary of cars and trucks. They own the left hand lane and will not hesitate to make a pass even if there is a motorbike in the car lane of the opposite direction. Instead of trying to make sense of it, just accept that you are basically on another planet where they've never heard of a DMV. Good luck!
