The number of people I see in cars on a mobile phone or txt'ng is shocking. They're drifting between lanes, I'm sure youve all seen them. I was wondering what might be the best way to try and stop them from doing this. Maybe some way of shaming them into stopping it? Do you reckon it is seen as socially unacceptable (like drink driving) in which case if you could let other motorists know that the person in the blue Honda is currently using their phone, would that shame them into stopping? I was thinking of holding my hand to the helmet in a "phone" manner and pointing to the offender might work. But it might look a tad silly too. Any other ideas that might work?
