Thanks McGrath, but I still dont see how you are supposed to make a note of the 0800 'how's my driving' number, when the said driver has just cut you up on the M5 at 50mph as much as I would like to let his employers know. Thats what makes it a silly sign.

In the back of my mom's car (I'd forgotten about this one)
'I brake for no particular reason'......I think its something to do with Terry Wogan. Moms 86 and still driving, infact she's off to Australia today - not driving, flying.
