You can use a hands-free device, but you can't dial the call? Well that just makes a ton of sense.
I've been out in the middle of BFE on the phone being talked into a place. Been in town like that too. Thing is, you don't have to have it to your ear the whole time. Every cell I've had had a speakerphone built in.
Yet another reason I am no longer driving for a living. I started saying it was getting too regulated years ago, when they took ALL the flexibility out of the hours of service.
