Replay Oblivion. The horse was terrible.
Aside from the fact that horses weren't exactly done very well in Oblivion, vehicles and horses tend to behave slightly differently, considering that horses are living creatures of flesh and blood as opposed to machines, and they have legs instead of wheels and all that...
I've noticed something your all failing to notice at least from my quick read through this topic, Fallout 3 did have a drivable vehicle. This vehicle was the J3xified drivable bike mod from the Fallout Nexus, now yes it was buggy but it exhisted and I was wondering why no one has brought this up?
Probably because it's a mod, thus not made by Bethesda, but by someone who could focus on that specific mod instead of needing to worry about all the other things that were needed in the game, plus, I think I'd rather have no vehicles at all than poorly implemented ones, and I don't hold much confidence in any fan-made mod that attempts to implement vehicles in a game that did not support them to begin with,
But yes, since it's been confirmed that no drivable vehicles will be in the game, asking for them is pretty pointless, considering that there's no way they could be added this late in the game and be done half way decently, in fact, if vehicles were added now, they'd probably be barely usable,
maybe in the next Fallout game we'll get them in some form, but I wouldn't expect it, and honestly, drivable vehicles isn't high on my list of things Fallout needs. The idea of vehicles doesn't really bother me if it's the right kind of game, but Fallout doesn't really seem like the sort of game that honestly needs it, often, it seems that in games that attempt to do vehicles but mostly focus on how the game plays when on foot, vehicles all too often end up being poorly done and you end up ditching your vehicle immediately if that's an option, and if you're forced to use the vehicle, then you're in for
pain. On the other hand, if vehicles were given major focus, the results I envision would be some sort of post apocalyptic GTA clone, and while I do like the GTA series and some other games that have similar basic gameplay models are also pretty fun, it is not what I think of when I hear the name of Fallout at all, I say it's best to leave the cars to the games that can afford to do them well. In Fallout, I suspect the closest we'll get to vehicles is something like the boatr in Point Lookout, or maybe something like the car in Fallout 2,
