That’s certainly a big issue and I think motion sensetive controller are a step in the right direction. I recently, well a couple of month a go, handed the PS3 controller to my mum, saying she should give it try – she has never played a single video game in her entire life – and as was to be expected she couldn’t figure out how to control the car, so I told her what to do. She then was able to accelerate and reverse but somehow managed to crash into each and every rock on the track. Then I turned on the motion sensor and it suddenly became reasonably easy for her to find her way around the track without crashing that often.
