I was just driving all my vehicles today and I feel as though motorcycles should have reduced space, they're a very overpowered vehicle. Most people don't make the 4x4 because its a lot slower and is harder to control, the few more spaces of storage still doesn't make it a comparable choice to the motorcycle. I feel like reducing the motorcycle space in half would be more balanced because right now there is no incentive to make the 4x4 besides completionist reasons. If not then i would swap them and make the 4x4 available before the motorcycle since the motorcycle is the obvious superior vehicle.
