The Government of Gibraltar has introduced a network of surveillance cameras on the border with Spain to capture images of queues of vehicles as they leave the Rock. They are in operation 24 hours a day and you can enjoy all the action here: Gibcams
Automation
In the UK, it’s fixed speed-trap cameras, in America it’s cameras at traffic lights. Automated systems, tickets going out to offenders without having to involve any actual policing. Both systems have been highly successful….at raking in money, but as to whether either actually contributes to road safety, the jury is still out on that one.
