I loved this game! It's crazier than crazy taxi! You should continue working on this and make it a full game. There could be more cool situations: a stage where you're picking up more cars and suddenly become a wider road and have to deal with the challenges of that, or a situation where you have to duck into underground tunnels or a situation where there's a parade through town and you have to pass over it multiple times!

I love all those suggestions! I have some ideas for the main gameplay loop too - was thinking of changing it around so that there's an overall timer (or a fixed amount of pavement) and you have to go pick up the cars instead of starting with them. When you get a new car, it has a specific destination assigned and if you can deliver it you get rewarded with something (extra time, or maybe money you can spend on upgrades or more time/pavement).
