Car Meets take place at the Airstrip where you can check out other players’ cars. You can see their designs and tunes, and you can download them if you like them. You can also take part in a showdown, a drag race to the end of the airstrip. You can enter in any car you like, and the lower the PI of your car, the more of a head start you’ll receive.
Can I prevent other players from downloading my design or tuning setup?
