I still believe in courtesy is contagious. Whether dashing to a checkout line and letting another go in front, getting up in a crowded seating area for someone more needy, helping a neighbor blow snow, volunteering in general. Been a long time since I got in a "go ahead of me" waving match at a stop sign.
Think of the positive advertising effect of Motorad developed commercial including a respect/ safety aspect? They got deeper pockets than MOA foundation. Or maybe co-ordinate the effort. As I see it, just don't see anything about the problem until statistics about the tragedies pop up on google. Which is too late. And, of course here when we discuss it.
As for school, was always told to treat others as I want to be treated. Didn't always work out well, but they did their part, the schools that is. Today, don't know how that would work out.
I am a huge believer in this and have seen it just in the 7 months I have commuted to my new job splitting lanes home everyday. The wave of thanks for those making room makes others want to help too. People naturally want to be liked and feel like they are good people. Maybe we have bad days now and then but in general people like to be part of a team of good guys at some level. Its why we made it to the top of the food chain. Waving and being reasonable and skillful really does make a difference. Aggression in any way percieved by others regardless of how justified is almost universally met with distaste by the majority of regular citizens. 99% of the time it does nothing to help and most of the time it just reinforces a car drivers alreay bad attitude. Thats why I carry grenades with magnets on them. Not!
