If it is considered legally dangerous to drive while using mobile phones then how much more dangerous to drive while pressing buttons and looking at a very small screen.
Shurely Sat Nav is even more attention distracting than any phone.
You don't press buttons on a sat nav whilst you are driving. The idea is you set it before you set off. As for smoking Mdoo98, I recently saw a lorry driver rolling a fag whilst he was driving!
This situation is getting out of hand.(pardon the pun) What happens when you change gear.......you take your hand off the wheel. And how many people do you know, especialy women, look down to see where the gear stick is!!! Does this mean to be safe you can only gave a car with paddle shift? Like a Farrari..mmm maybe not such a bad idea after all.
