Nice concept with a substantial amount of execution, considering the time limit. The buildings jumping to the beat was a nice touch! A lot of what separates this game from greatness has to do with tweaks and fixes; the core concept is clearly here.
First, the gas cans can be difficult to see on the horizon (I moved to <6ins from my monitor and still couldn't consistently see them) and clicking on them can be difficult even when they can be seen.
Secondly, a readout for speed, even in general terms, would be very appreciated, as it wasn't super clear how fast I was going relative to "normal" and how that might affect things. A little bit of context would make that mechanic do a lot more for you. While we're on the subject of information telegraphing, I'm still not 100% on whether or not the driver followed my prompts for clicking on the road.
Finally, critically, while the driver's AI is actually pretty respectable, he didn't seem able to deal with the constant fishtailing and regularly made bad decisions with or without my input, resulting in about 2/3rds of my runs ending because he zigged instead of zagged, rather than because of a choice I made.
