Topic: Help for 7 yr old with Autism

I’m 60 years old and have never played a video game. I am raising my 7 year old grandson who has Autism. He loves driving arcade simulators. The car jumps and lands but never seems to get stuck. Someone last year at a store talked me into an Xbox One, Forza and a Ferrari Thrustmaster steering device and we mounted it on a seat. Looks good but he isn’t developmentally able to back up/rewind yet so he gets frustrated and won’t play it. Can someone suggest an easy game that will work with this thing? Any help would be so appreciated.
