That's a very good point. Go and pick a nice safe stretch of road where it's safe to make brisk progress (eg. pass lorries, towing vehicles etc) and then install an average speed kit over, say, two miles. You'd make a mint.
I'm interested to know how evidence from such cameras stacks up in court. Has it been tested? In my opinion I think it would fall over as there is no actual photo of the offence being commited. If the start/end cameras took a piccy of your car/bike and it was below the speed limit I can't see how a mere calculation can be used as evidence for a conviction.
For example: distance between the cameras...
1. Was the tape measure or other device calibrated?
2. When?
3. By whom?
4. Did that person have accreditation to calibrate it?
See my point?
Anyone fancy a sprint along the A43 in Northants to test this? |
