I'm saying that people in general tend to learn much better those things that matter to them.
Learning which color means go and which means stop matters to a driver.
Learning to look for moron through cyclists passing you on the right as you're slowing down to turn right matters much less to a motorist.

And Al, in response to an earlier comment, I know that cyclists can be right hooked from motorists turning right from the wrong lane, but for a VC this will only happen if he's going straight from a through lane, or a right-or-through lane, and the motorist is turning right from a through-only lane. What do motorists need to be taught to know not to do that that they're not already taught? How many motorists do you think who do that don't know it's wrong? How can they not know it's wrong when they're going against a painted stripe on the road? If they're THAT dumb, can education help at all? If they already know it's wrong, what's the point of telling them again it's wrong?

Once again, I question the effectivity of educating motorists about making cycling safer. ZZZZ... (for the motorists).
