Yes, there could be an overlap, then there could also be not. I doubt T&P is the only driver capable of realising that phones and motion do not mix though often it seems he may beBut there's surely going to be a high degree of overlap between these two groups of people? And if someone is dumb enough to drive whilst at speed, they're probably dumb enough to continue a call when the lights change

So in the case of mobile phones and traffic lights I think the police & lawmakers should address the actual problem and nick the ones that are too stupid to finish the call when the lights go green, rather than nicking everyone on red on a presumption of what they're going to do.
