For a lot of people the SatNav seems to have removed the ability to read road signs!!
There's nothing wrong with using a SatNav as an AID to getting where you're going as long as you don't rely on it - and remember to update the maps occasionally (Dunkerque Guzzler?).
Maybe extending the barrier to the top of the hill would help, or at least a lot further up. It's not the first time this has happened and one day some poor s*d is going to end up wearing a 40-tonner as a bonnet badge!!
