I can play these kinda games for hours lol. Sometimes you can get into situations with no way out, especially in the slow lane, maybe a permanently empty lane in between each lane so there's always a space to safely move into, but those lanes don't give the player any score (or maybe even remove score if you drive in them for too long) could be a solution. The hit boxes are too big and seem inconsistent, for a game like this I think you should make the hit box for the player slightly smaller than the actual player sprite so the player feels like they are pulling off some close calls (could even include a combo bonus for chaining together close calls). Having this game in portrait orientation would be better because you'd be able to see further ahead and have more time to react to incoming cars, currently if you are moving fast, especially in the fast lane, there is almost no time to react. Also I should be able to press play with the space bar from the main menu so I don't have to keep switching from keyboard to mouse and back, but that isn't a huge issue. Overall I had fun playing this, and with a few small changes I think this could be a really fun game, nice work
