When I was younger I liked to stay in constant touch with my mum when she went out. It got so bad that I started phoning her when she was driving, she had to keep pulling over to answer the phone every ten minutes. In the end she bought a . . . hands free kit thing I think . . . and this wired up the her car and when I phoned it automatically muted the stereo in the car and answered the phone after three rings allowing me and her to talk while she continued to drive. It worked well
As for drinking and driving to my knowledge my mum has never done that. I haven't either. Driving required so much concentration that sometimes I had to turn the CD player off in my car, doesn't matter now though as I no longer have a license. I miss my car and being able to drive
