Good game, but needs more vehicles faster

The game is fun and addicting. Great graphics add to the experience. I have two problems with it.

1. Need to come up with new vehicles faster.

2. Some of the missions are impossible. Difficult is one thing, but when the vehicle doesnt have enough gas to make it to the next tank regardless of driving practices, it kills it.

Fix these two small issues and it will be an awesome game.
