One hears again and again, acceleration is fun. I wonder why? A motorcycle with 100 hp or more almost creates earth acceleration: 9.81 M/S2, i.e. after 3 seconds it is from 0 to 100 km/h. Great. I can just lie on my back and feel the earth’s weight. I don’t know what’s interesting about it. At 9 or 10 G I’m dead, probably more likely. Is it not much interesting to feel “gravity”, i.e. swing down a pass without positive or ne Gative acceleration? Or is there something physiological? When I flew, the 60° turns, where I had more than 2 G, were rather unpleasant…
