Stupid stupid people

In one of the free London rags tonight there's a story about an ambulance crew who followed their satnav to Manchester instead of London and didn't notice their mistake. For fucks sake, how do you possibly not realise something's wrong when a thirty minute journey suddenly takes eight hours?

Worse than that though, some dippy tart managed to get on a dual carriageway by following her satnav but on the wrong side of the road, which let's face it makes her fucking stupid. The fact she got two thirds of the way to London driving down the fast lane the wrong way? That's just plain scary. Seriously, people that stupid shouldn't be allowed to walk around town without a helper.
