I recommend a two- or three-tile motorbike made of extra-light frames with an engine in maybe the 1.5- to 2-liter range, a motorbike alternator, a motorbike battery, a small gas tank, and a relatively light matched pair of wheels, as well as a saddle instead of a seat if you can find one. (Don’t forget a muffler for noise control.) For light, install a forward headlight and a floodlight, because you’ll be sideswiping shit like crazy and running into things every time you turn if you just use a headlight. For cargo, I recommend a cargo carrier for its 1000-volume capacity in one tile; if you want a separate compartment for gear and supplies as opposed to lewt, I put a shopping cart basket on the front.
Why do I recommend this? Because it’s not a waste of gas and it’s small enough to navigate around all those goddamn wrecks in the street, that’s why.
