Scarily enough, we did actually hit a pram last Sunday while out driving. My wife was in the driver's seat and there was a woman coming from the opposite direction with two small daughters, one pushing a pram. The pram pusher was very cavalier and flung her pram into the road where it was inevitable our car would hit it. My wife almost screamed at what she feared, slammed on and her knuckles went white on the wheel. I noticed, earlier on, that no-one real would be hurt as it was only a dolly in the pram but there's a moment of pure terror once you realise a collision is inevitable. The pram was virtually undamaged and the mother was very unimpressed with her daughters pram-steering skills. Still, a nasty moment there.
