All vehicles support.
Basically support for air, space, sea and land vehicles. Just like in SP and KSP.
they wont make simple boats/cars because there woudnt be much content. Think about it, a whole solar system to explore or a small track?
Well, there are wings*, and the fuselages have a buoyancy* setting. And the games are revolved around rockets*. They also added wheels* so...
Or we could just ask for simple engeering, which would include EVERYTHING
Best suggestion ever =)

I wish I have more votes for this one =(
This is kind of needed if you are forming up a space program. We need pieces from SP to make space planes. We need wheels to make rovers. We need floating stuff so we can land on water.
this aint really going up to name. its better to ask for simple boats simple cars added onto the Simple line of games
