Unless you are a hermitt, dug into a crater, and set in her ways, you will want to get around the wasteland. Most gasoline has long since evaporated in the tanks, and changed into a useless dark black sludge, clogging up the rusted fuel sprayers. Before the war there where some development in hydro powered and nuclear powered engines, and sometimes you can find a working vehicle that runs on Energy Cells. Expensive but worthwhile. The engines are build into the bodies of state of the art ’50ies huge cadillacs.
But the most wastelanders get around on muscle powered vehicles. Pony and dog carts, bikes, and ofcourse walking.
Slavers sometimes use handbuilt vehicles creaking on wooden wheels, pulled by their unfortunate victims.
A invention by the US army, created to conquer the long distances of the Canadian Artic, without long supply lines. This is a nuclear powered, vertically take-off, helicopter, nearly fully self supporting. Big enough to hold up to 12 soldiers and all their equipment. Some are left over, and in the hands of The Brotherhood of steel unfortunatly they are unreliable, and prone to break down in midair. Wasteland technician, at this stage, have barely enough knowledge to keep them flying, but not in a safe way.
Nothing as mundane a horses really exsist anymore, but riders still exsist. Cochry a huge, tame mutated lizard is being reared and some of the more fashionalbe upside cannibals and raiders are already spotted astride these huge, dangerous looking beast.
