I would be very tempted to say something...mobile phones are my pet hate...I saw someone swerving along the road - he was on a mobile phone!! I would be a bit scared to say something, because as I woman, I would feel vulnerable - my work pal was driving home from work, some idiot was driving stupid..but she had enough time to pull out in front of him, he beeped at her, from way back, flew past here honking his horn - she did the v sign...for the rest of the journey, he decided to follow her, up her backside, around the side of her, she didn't know if to go onto the motorway, or to go home, he actually followed her home, she pulled up outiside her house, he drove past, turned around and came back - there are some idiot drivers out there..and I hate it when you don't see kiddys strapped in, fair enough, as a driver, you might not give two hoots about your safety, but you should think of your childs - its important!! Good on you though for saying something - it may make him think - hopefully!!
