The AA was founded in 1905 as a speed-trap spotter for motorists who wanted to avoid being prosecuted for their law-breaking. The original spotters were cyclists. In 2011, cyclists could be spotting for the AA again, but this time on the right side of the law.
Cyclists, and anybody else, can sign up to complete an AA/Populus survey of motorist behaviour at road junctions.
AA suggests volunteer survey takers remain inconspicuous.
The survey can be downloaded online and, once completed, has to be submitted online.
The behaviour to be monitored is seatbelt wearing, mobile phone use, indicator use, defective brake lights, and perceived excessive speed.
The survey - which would take about an hour to complete and should record the driver behaviour in about 100 cars - should be carried out in daylight at a road junction at any time from now through until 9th May.
There's a prize draw, with the top prize being £500 and the second price, ironically, is a go-faster session on a race track.
Chris Peck, policy co-ordinator at CTC, welcomed the survey:
"This is a good opportunity to reveal the level of bad driving that goes on," he said, adding that in previous studies, 48 percent of drivers broke 30 mph speed limits.
