HOWEVER... Well stated. If there are vehicles in the game, even something that flys, that would be cool..... AND you don't like vehicles... You CAN still play the game, the rest of us wont ban you.....
You MUST however agree to one rule. DON'T DRIVE ANY VEHICLES...... If you drive any vehicles, and you don't like vehicles then you will negatively impact your overall enjoyment of the game...
NOW.... If you hate vehicles only second to hating the fact that someone else that likes them may get some enjoyment out of them; well then you are an idiot and really should reconsider playing games at all, and in particular online games as this may result in your being unhappy; watching all of those people out there enjoying things that don't appeal to you.
Just my two cents.... Well in re-reading this.. More like my 5 cents

No, as an RPG the game has to have options for the player. Stop being ignorant. Borderlands is not the game we want to play, we want to play Fallout. Vehicles would give us more options and that makes RPGs more fun. So instead of taking the fun from the players, if you don't like vehicles then don't use them. Simple as that.
