1) Yes, in rental cars in my youth
2) No specific training though.
3) I have been know to practice "Tactical Driving" while in my Ford F150 if there is a Smart car next to me on the
highway though. I know it isn't right but it is just a "gas" to see the driver of the smart cars face change as I
"Change lanes."
4) While driving in the UK I used "aggressive driving" skills which seemed to work quite well especially while using
a "rotary" to merge to a different highway. Apparently their rotaries go clockwise while USofA rotaries go
counter clockwise. Who knew?
