Most of the comments here are from blokes, with a few not very informative inputs from the ladies.
It is my observation (as a bloke) that most women, especially experienced Mums, can multitask very impressively. I can't and don't answer the phone on the move, and even stop talking in traffic.
I have, however, seen my own Mum knitting to a pattern on one arm of her chair, a book on the other, litening to/watching TV, and joining in with any of several family conversations, all at the same time. There wouldn't be too many guys who could do that, so how about some thoughtful input from the ladies.
It is just the dangerous bit, the 65mph, that is horrifyingly stupid, isn't it.
Isn't it?
