Another reason I think they might be disguised horses is that they don’t act like minecarts or boats in Creative mode. That might change in the future, but as far as I’m concerned, it’s not a big deal. One other thing that might be a little weird about these vehicles is that they don’t use fuel (again, like horses). But the vehicles from Personal Cars can handle most terrain just fine. Their turning radius is a lot bigger than that of horses, so they feel a little clumsy compared to horses – as they should! Horses remain superior in handling on very difficult terrain (steep hillsides, thick forests) and are better for exploring because you can always dismount a horse and guide them with a lead (when fording a river, for example).

The vehicles in Personal Cars, on the other hand, handle almost all terrain like champ (a champion racing stallion, that is). Even its plains and desert biomes are pretty bumpy and unpredictable. The problem is that Minecraft isn’t usually too terribly flat. So in order to use vehicles from many (if not most) earlier mods, you needed a big stretch of flat, featureless land. See, in mods where vehicle behavior is based on a minecart or (especially) a boat, the vehicles sometimes have a tendency to break if they come across a kind of terrain that it just can’t figure out. It solves the problem of stability of the vehicles, not only in regards to their movement on land but also in regards to their persistence in the world.

Whereas earlier mods that added cars tended to make vehicles behave more like boats or minecarts (or even a mass of moving blocks – usually VERY unstable), Ktos94852 appears to have patterned the mechanics of the cars in this mod after Minecraft’s ridable mobs, and I think that is brilliant. I suspect that’s because, under the hood, they are, basically, horses. How do they drive? Well, once you figure out that you have hit ‘R’ to turn the ignition before you can move them, actually, the cars all drive kind of like horses. The key modifier takes an already existing key and either unpairs it or assigned its pairing to another key, making a duplicate (for significantly less money than the $300 Ford wants to make me a second key for my Focus). They are also used just to whip mobs and players, which is hilarious. Whips are used to load and unload mobs onto and off of the transporter. Without the key to unlock a vehicle, the vehicle cannot be used. Vehicles are entered and exited the same way you mount and dismount a horse (right click and left shift). Right clicking the key locks or unlocks the vehicle. Each vehicle must be assigned a key (you can make duplicates).
