Again - the issue of incomplete (or wrongly interpreted) data is not unique to C&RT.
Our local ASDA applied for planning permission to install CCTV enforced parking restrictions. Two hour limit, no return within three hours.
(Two points; they needed planning permission for the cameras and the signage, not the use the images would be put to. Second, they are next to the railway station - a lot of London commuters used ASDA to avoid the station car park and £7 a day)
Most local residents supported the application, citing difficulties they had with parking and shopping.
After the CCTV went live, a huge number of local residents got booked. On investigation, most were quashed. A typical story was "dropped wife at ASDA, went to B&Q (two miles up the road), came back and picked wife up". Two visits, each of five minutes but within three hours of each other.
So, the locals had interpreted "Two hour limit, no return with three hours" in a different fashion to the parking company. We've now got it (I think) agreed as "no more than two hours in any three hour period" - whether they can actually reprogram the computer to action this correctly is anyone's guess.
