Bigger than a wombat by the look of it. Hope they took the meat home. There was a Citroen CX hit an elk at speed a few years ago - in Sweden I think. There was major damage to the front of the roof (ouch) but they could still drive it and yes, they took the meat!!
Serious air horns! If the driver had hit the horn in time, that porker would probably have landed on the roof!
