I am not doubting that its brilliant but the fact is that the average user of sat nav does follow the instructions to the letter and forgets that the highway code overrides these devices by law, so this idiot needs to be made an example of and serve as a warning to users of these devices.
The problem is, most of these things are programmed from a database that has been generated from images from space and these devices have mistaken many footpaths as dirt roads.
They are brilliant but flawed.
Anyone putting 100% faith in to one of these devices really needs their heads searching. Me despite my lust for technology draw a line at this type of technology I am most certainly old school when it comes to navigation.
I understand that they do make rather good MP3 players, those that can play mp3's but apart from that, no thanks.
