agent elevator writes: Lawrence Ulrich at IEEE Spectrum has an interview with the maker of a simulator for professional racers. The Motion Pro II from CXC Simulations costs racers $54,000 and up. It conveys amazingly fine sensations, including the feel of the car's tires wearing out or the car lightening as its fuel dwindles. It also has the kick to make you really feel a crash: "If you hit the wall in an Indy Car and don't take your hands off the wheel, you'll break your wrists. Our wheel is a one-to-one replication of that, but we don't turn it up that high. It's the first time we've been able to replicate racing forces so high that it introduces liability questions."
