If you ever get an NIP for a GATSO using the lines on the road get the pictures so that you can calculate your speed yourself to check up on the calculations from the speed tax office if you think you have doubt over the speed.
There will be two pictures, hence two flashes. The time period between the two flashes is set/known. The distance travelled is known. Time period is known hence the speed can be calculated.
