I wish it wasn't the case though, I thought it was hilarious how you could shoot the pony pulling the cart behind you. I was expecting to kill him and the cart to stop... instead I was rewarded with smaller vehicular explosions.
Definitely WTF, but awesome nontheless. I'd love a mission or diversion where you could race gimp chariots, maybe with reins in one hand and a melee weapon in the off hand to fend off other drivers. Imagine blazing throught the streets of Steelport, with a team of lathered fillies in front of you, beating off (pun intended) your competition with your purple-headed warrior's implement, with Zimos managing your pit crew.
