After the crash there should be a "RETRY" button not just "GAME OVER" pretty frustrating when you have to Reload the web page to retry, other then that, games quite simple

There are many problems with this game, but I'm too lazy to type them out. The only advice I will give you is: Don't upload things from Scratch.

There was an attempt. Music, Sounds, Animation, Objectives, these are things a game needs. At the very least you could have the background layer (the roads) be scrolling down and repeating. Don't scrap this project, if you keep adding those things I mentioned, it can be something fun!
