Dont the goverment realise that some of us can actually multitask and are quite good at it..
Some cars can do 150mph as safe as other cars can do 70, and brake in half the distance of a normal car at twice the speed.... so does that mean the NSL for motorways and dual carriageways should be increased to 150mph?
Just because some people can multitask and multitask well doesnt mean everyone can.
And it doesnt matter if you are good at mutitasking, when you are using your phone, you will never have full concentration on the roads, the split seconds you are reading a text, looking for a number, answering the phone can make all the difference between you hitting a child and seeing that child run out onto the road in just enough time to break.
And technically, the human brain cannot multitask at all, it only has one thread for thinking, you cant think of two things at once, its one thought at a time. Which will ineveitably delay your reactions on the road if you are busy doing other things.
