I started this project AGES ago, but then I couldn't figure out how to make it work, so I moved it to the trash. One year later, I was looking through the trash (not sure why) and I found this. At the time, I was a much better scratcher than I was when I first started it, so I thought I could fix it. And I could! Arrow keys to switch lane. Avoid other cars. Update! Just made it look like the roads are moving. Suggested by @datboiforlife
