cheer, this is prettty good.

yes but IRL the tracks are powered! Tank tracks can weigh several tons and require several hundreds of horse power just to get the vehicle rolling. Wheels have close to no resistance in weight, so having tracks on a vehcile unpowered is just carrying dead weight adding loads of friction. The tracks in stormworks are pretty much just wheels with added tracktion and some more torque requirement. But IRL, the only option for an unpowered trailer is wheels.

At least in real life it wouldn't have any benefits at all, so I'm keeping it realistic and using wheels. Don't know if the game accounts for the weight resistance from the tracks like it would IRL

Because tracks are a waste of friction when not powered.
