This is neat!
One thing I'd like to see is the addition of some type of hazard that rests on the ground (like a crack or hole in the road) that forces the player to jump. This would serve to reduce the downtime between needing jumps, as the bouncing car-pocalypse must often be avoided by remaining grounded, which leads to some long stretches of downtime.
I really enjoyed the art, especially how the little man looks like he deeply regrets his current life decisions! Some speed lines when you pick up the coffee might better communicate the increase in speed though.
Great work all around!
