Is it possible to get someone prosecuted if you film them on the phone whilst driving? When I'm walking back to the car after work I probably walk past at least half a dozen people on their phone in slow moving traffic, on a hugely busy road with pedestrians everywhere, really grinds on me!
It's always nice when someone acts like a complete tool on the road and obviously forgets they're driving round with their business plastered all over the car/van.
