There is a lot of room to improve. I can't believe that a Model S falls backwards if you try to climb those mountains. This doesn't represent the real performance or behaviour of the actual cars.
Please make the character faster or be able to sprint... walking any distance is hopelessly slow.
Also the car should engage handbrake if you are not pressing any key, but it doesn't stop even when you get out.
And some decent skybox would be appreciated.
