Subject: Another sat-nav accident: car destroyed, driver escapes

Accepting satellite-navigation directions without sufficient thought has caused another accident. A young woman in Great Britain followed its directions onto a country lane which was blocked by a gate. At first she thought it was a dead end, she said, but "the sat nav insisted it was the correct way so I opened it and drove through."

After the first gate there was a second one, so she got out to close the first gate and open the second one, apparently not thinking about why there might be two gates across a road, or why there was a sign saying to proceed
"if the light is green". (None of the news reports I found says any more about that light than that the sign existed.)

while she was out of her car, a train came along the tracks and demolished it.
