So you're saying that even though you're moving slowly, it's still ok to use your phone while driving? What if the driver in front of you brakes suddenly and you crash into them, because you were too busy yabbering away not to notice? The law is the law for all speeds for a reason; you can still cause a fair bit of damage to a car even at 10 mph.
If I'm in the car with my husband, he'll answer the phone for me and I'll do the same for him, but if I'm on my own I plug my handset in. It really ain't rocket science to use the handset you get with your phone and Bluetooth sets are mega cheap these days.
I'm currently training to be a driving instructor. I gave the guy at the interview a good laugh when I said one of the reasons I want to do it is because I'm fed up with the amount of numpty drivers on the roads. I don't claim to be the best driver in the world but as soon as I see some eejit with their phone glued to their ear and doing 40 on the motorway it does make me want to shout at them.
