You right Dave,(&Darrsi) there's no excuse. I think long term it won't be an issue as the technology is being integrated within the car. E.g. your phone will automatically link with the car and all calls will go to car speaker with the caller's details displayed on the dash. In the meantime it seems as if we need to suffer these idiots.
Treat everything in life the way a dog would- if you can't eat it or foc it, forget it.
