Nice entry! The main mechanic seems good enough to keep me enternained for a while (got to level 10 after several tries). I found some unhandled situations, I guess: in one of these my car kept crashing against other at the end of the very first level due to automatic acceleration (cool as level-cleared cinematic but problematic as it forces fail when you already have beaten the level). In other situations some random truck crashed me from behind with no warning, and this may be ok (though it's weird that other cars do seem to respect their ways) but I would put some rear mirror to keep track of incoming hazards. I also ran over many pedestrians may be due to the lack of visual feedback, and I know it can be intended as part of the challenge, but I think clothes color can be improved, or at least putting the direction arrows on the floor plane would help, as standing vertically messes up the visibility a bit.
So here's what I think: nice concept based on main premise. Yes, may be is not super fun, as the only real skill that this challenge expects from you is to wait and be patient (yet with some enjoyable moments), but on the other hand, the execution stands out, very well implemented overall. Congratulations!
