As others have said, good luck; it's a mindset, and nothing short of catastrophic trauma will change it. A whole TON of people believe that bike riding has no rules whatsoever -- it used to bother me a little bit, as i felt that their erratic acts would 'convince' drivers they're right to try and chase me off the road...but it hasn't, and likely won't. So, as long as they don't steer into me or mine, it's a Darwin thing, AFAIC.
