Solid start, the idea of car jacking game is nice and you got some good core mechanics going! I did do a better job the second time I tried to play but the driving still feels a bit clunky and difficult, to the point of frustration.
3 minutes are very short when sometimes you randomly spawn at the other end of the map from your extraction point, and have such a long distance to drive, whilst other times the spot is quite close by. It would be nice I think to make sure that, if the timer runs so short, you're always within a reasonable distance.
A few small polish elements could improve the experience a lot. For low-effort improvements, I'd suggest randomizing the car colours between a few colours (using a white base car and the self_modulate property) and adding a few sound effects. Music and sound improve a game considerably, and if you spend an hour on that you can already get in a lot!
Nice work, you've implemented a bunch of cool systems!
