Being able to talk to someone from a moving vehicle is now so common I don’t really think about it anymore. I do remember a time when it would be surprising to reveal to the person I was talking to that I was currently driving. They would say
“Well I better let you go so you can go run those errands you talked about.”
“Oh, I already did all of them while I was talking to you. I thought you would have caught on when I said ‘I’ll have a number 3 with root beer.’”
