This won't do much for people under the influence, but I think part of drivers training should involve what to if you do if you pull out or make a left turn in front of a motorcycle. A problem that I have personally witnessed is people who pull out, then see the motorcycle and stop, blocking the entire lane. I say if you find yourself in that situation, you should finish the turn. That may give the cyclist time to maneuver behind the vehicle. As it is now, nobody knows what to expect from the other. A standardized procedure even if it only worked 1 out of a 100 times would be better than what we have now. My 1/2 cents worth.
