Those people who ignore the rules and put lives at risk must surely have a total disregard for the cost of a rescue. They must also have plenty of money as they can afford to "kill" a car by driving into the North Sea. I don't think that in circumstances like that , their insurance company would cough up because their actions were self afflicted ,as it were. Brettly, most rescues are by lifeboat, occassionly R.A.F. Boulmer may be called, or if the helicopter is active in the area it may call in to offer assistance, usually if there is someone injured. Barriers are considered not an option as there is a risk that someone will be trapped on the wrong side of them. A warning red light, coupled with details on car park tickets seem to be the prefered deterent, with those who ignore the lights (which would be red outside the safe crossing time) being prosecuted. £4,200 = 5 years wages, Brettly. That is tantamount to slavery. Its a little over £800/year
