Typing games are always fun and yours was no exception :)
I think a few things could have made it more fun / clear:
using real words instead of random letters
something that forces the player to dodge every car (maybe that means fewer cars, or cars that spawn in the same “lane” as the player). Due to the randomness, I sat to let several cars pass before having to do anything.
Using green text instead of red. I thought I was doing something wrong.
