it was a joke... just like the avengers should stock pile a bunch of beater cars in case of an ultron emergency... hell for that matter they should just hand over there ultron contract to ups or something and they can use delivery trucks against him... have a color business presentation but a black and white budget? ultron threatening to take over your planet? just call the ups store and we ll send someone with a stick and a ups vehicle out within the hour and deliver your presetation to you at no extra charge.
