Note that, in the UK, while you may use a bluetooth headset while driving, you are not allowed to even <i>touch</i> your phone - whether to update the satnav or whatever, especially not to hold it to your ear - without facing a driving citation.<p>Someone was also stopped (and given penalty points, which add up to a ban eventually) for driving with promotional writing on the windscreen (the sales rep, who was also in the car for the test drive, offered to take the points and was very nearly charged with perverting the course of justice for it.)<p>It is not surprising in the least to anyone who drives here that this would be the case - glass is a visual distraction while driving, which blocks your view of the road.
