I was behind a "Baby On Board" car, blonde driven, which was very slow off the lights this morning, and continued very slowly making a RH turn through the intersection. As I came around on her left I could see her talking to her phone.
It seems these dills have decided among themselves that mobile phone use is OK if it's on speaker and they just hold it in front of them in one hand.
I guess we can be thankful that most cars these days are automatic so they are able to do the one-hand driving trick. Otherwise the "shoulder-holding" phone style would make their driving even more erratic as they tried to reach for the gear stick.
