The vehicles function as any mount in the game except they are much faster. They’re a little bulky but that won’t stop you from getting around easily. They are very simple to drive and don’t break from simply bumping into a wall. They do have damage though so be aware if you fall from a great height, you may lose your car.
They will drive on any surface and even up blocks so long as the path is only one block height difference from the previous block. This makes scaling mountains a breeze. But obviously they will travel best on well laid roads.
