The best advice my Dad when he gave me a Honda CB/CL (it was both) 350 to ride (he also never gave it to me, says he) was that everyone, EVERY ONE[!] is drunk and out to get you. Never trust anybody in a car.
That advice has served me well whether I'm in a car or on a motorcycle or on a road bicycle. Everyone is trying to kill you, ride/drive as though they were. In 40 years of driving something on the road I've had one accident and it was when I was pulling a Uhaul trailer and couldn't get out of the way.
I really miss my ol' Dad. He'd really like the BWM F800GS until he found I bought with his money ;-)
