Here's a news flash... it does!!!... as I nearly found out as I picked up Caroline from the railway station when some woman looked as if she was going to turn right, and even started to turn... and then suddenly went into the space I was headed for. I gave her the dirtiest of looks, she just looked away and carried on having a laugh with the person on the other end of the phone.
Personal hands free kits are so flipping cheap nowadays, it's a constant wonder to me why people do not use them... especially company CEOs in their Jaguar S-Types and personalised number plates (as an example).
It's not big and it's not clever, and I have the right to be able to drive down the road and not be endangered by your pig-headed stupidity.
