When I was in Iran there were people who made a living getting hit by cars.
One didn't make it. He assumed that cars coming out of the near end of a gas station would be doing about 10 mph when he stood up and stepped out in front of them.
One of the other Americans there had pulled out of the Far end of the gas station running flat out in his TR7. There is quite a difference between 10 and 50 mph
Unfortunately it hurt the Triumph pretty bad
