Movable speed indicators have been in Abingdon for nearly two years, but this is the first time I’ve seen one working so close to a long-standing speed camera. This is on Audlett Drive in Abingdon, where the limit has recently changed from 40 mph to 30 mph.
While I watched for a couple of minutes, all the cars were at or under the 30 mph limit.
Which works better: the carrot or the stick?
