I really dig the setting here, what a cool niche to explore like this.
I think you did really well to take a simple mechanic and make it fit really well to the action happening and have a knock on effect. For a game with only one button I felt like a lot was happening and it ended up feeling quite tense (in a good way) when the car rolled in. The different zones were placed well because it felt so satisfying getting green but I kept _just_ missing, and having the bar sometimes go the other way after you hit kept me on my toes!
I really liked how much character you added to the art. everything looks pretty nice and fits well together but its the little bouncing of the speaker as the drivers words come through and the animation of the player and the spotlight effect that elevate it.
I enjoyed this and wanted to play again to see if i could do better, but it got a little funky on a replay (i was on race 6/5 then nothing happened). its nothing i don't think a refresh will fix, but I'm determined to do better than p3!!
Overall i think you picked a really interesting idea and executed it well, congrats. thanks for sharing!
