Why is it harder to miss than hit?

There was an entry in the Guinness Book Of Records, years ago, which said that the most isolated tree in the world (in the middle of the Sahara, hundreds of miles from anywhere) was no longer there. It had been knocked flat by a French Army lorry.
The son of that driver is obviously alive and well and driving tractors in the Golden Valley as he managed to hit this pole which supplies our electricity. As you can see, it has been repaired but not until we'd been without any power at all for 17 hours and the the power surges before we were completely disconnected had fried one laptop computer, a DSL filter and our central heating!
The guy was ploughing with headlights at 7.30 in the evening and obviously couldn't see the cables and the pole. Hope he's not allowed on the road!
Everything is sorted now and we're warm again (2 days later)

The joys of country living!
