Would you rather of a pre-built car (vehicle) or be able to make your own? 4
Make it on yourself (2) 50%
Pre-built (2) 50%
I think it would be interesting to add a re-sizable frame which have collision with the ground that you can build on. You would be able to put pre-built items on it like wheels, (without engine no movement) engine, and a steering wheel. The point of this is so if you want to you could make your own car or other movable object, but i would mostly like to be able to make custom ride cars for like a theme park, so i would like a way for them to link together too. So in theory you could also make a custom train with this.
Also, i think you should be able to link wheels on the ground to some sort of engine or motor so that you can generally make something like a chain lift with wheels.
