I've seen many Vehicle posts, but they have all been a bit too ambitious, not to point any fingers. But anyways, for the most basic thing, why not a car of sorts? My idea is that it would control in almost the same exact way as on foot, except it basically acts as if you are on ice. You would have to be careful driving it, and where you drive it because the vehicle would have a health of its own, as the vehicles health decreases it slowly becomes slower and slower till its slower then actually walking. When your vehicle runs out of health it could either 1. Set on fire, giving you about 10 seconds to get out and retreat to a safe distance before it explodes, killing you instantly OR 2. Exploding instantly and damaging you for half your total health. You could make different types of vehicles, like an Off-road one that works wonders on dirt, grass, sand, etc, but is terrible on roads, stone, etc. And add one that is great on Roads/stone but is terrible on everything else. Boats would be pretty self explanatory, but that's just being too ambitious. Flying vehicles would just be pushing it, thanks for reading and/or (If you think its a good idea) voting.
Oh, I forgot to mention. You could make it so if you crash a vehicle it does a bit of damage to it, im dumb for not mentioning that. And you could make it so if you total your vehicle, you either have to get a new one, or you can spawn it after a cool-down. Please go with the latter if you consider this, but if you do go with the first option, make it cost gold please. Not plat.
