I'm glad you've enjoyed the game.

After the game's full release, I plan on launching a crowd funding effort called "Feature Bounties" in which donors vote on what we implement, and when we raise enough funds we'll implement them.

New vehicle types, such as the motorcycles, buses, semi trucks, tanks, and many others are some of the bounties. As are many other gameplay features and improvements.

The problem with artwork is that it's something I can't do my self, so I have to hire an outside contractor which costs a bit of money. So the bounties for new vehicle designs will essentially be what I pay for them.

Many thanks for the reply. He finds an idea very interesting and I know how expensive and difficult it must be to develop such things. I'm waiting to help you!
