In Brisbane the bus drivers wave! I think it's cool! Of course this particular bus driver does look like santa.

Ever think that trucks and buses pass closer because they're significantly wider and take up almost all the left hand lane?? (Sorry, RIGHT in the states)

They shouldn't have been included in the analysis, or if they were in his article it would have been better if the above was mentioned. or even some data from hos Automobile Club, or the government suggesting just how wide trucks and busses are thereby strengthening his data that trucks pass too close.

I get spooked in my car when a truck over takes me because of how close they pass.

As for the unhelmeted thing, I'm guessing they're more afraid of hitting an unhelmeted rider because they're more likely to die in a crash and put them in jail for life. O_O
