Fun game! :D It's great that the car decelerates so quickly, to give the player enough control to avoid unnecessary frustration from hitting pedestrians who just manage to run in front of the car. (I was wanting to beep at them to clear them out of the way--perhaps that could be a feature!)
I love the sound effects and the colours.
As Ducky has said, it's a shame about the lamppost collision, but these things happen, and once the player knows, they can make sure to give them a wider berth.
I did get a bit of slowdown towards the end, when I had 120 pedestrians--I'm not sure how polygon-heavy they are, but with them being small and fairly uniformly green, perhaps they might be able to be a bit lower-poly.
As Ben said, the drifting is really fun, and it'd be great to be able to go at high speed and do some intense drifting, and having some kind of points system like Maria said would certainly ease frustration when hitting a pedestrian, so the fun isn't immediately over. I love the slowdown effect when that does happen, however!
Well done! :D
