Rigorous tests We subjected the speed gun to rigorous tests.
Pioneers It is often overlooked that throughout the nineteenth century, most of the electrical experimenters, inventors and engineers who made these advances possible had to make their own batteries before they could start their investigations. the World was starting to emerge from the Stone Age. C., Mesopotamians (from modern day Iraq), who had already been active for hundreds of years in primitive metallurgy extracting metals such as copper from their ores, led the way into the Bronze Age when artisans in the cities of Ur and Babylon discovered the properties of bronze and began to use it in place of copper in the production of tools, weapons and armour.
In our tests, it wrongly recorded a wall as travelling at 44mph, an empty road scored 33mph, a parked car was clocked as doing 22mph and a bicycle (in reality being ridden at 5mph) rocketed along at an impossible 66mph. is used in nearly 3,500 mobile speed units hidden in police vans or cars and mounted on motorbikes.
Speed traps - nearly half of which now use laser gun technology - reap more than £100 million each year in fines.
In other tests, we found the equipment was measuring the speed of overtaking cars instead of the one being targeted.
Today, the Mail can expose the scandal of a speed enforcement industry in which the collection of fines is considered paramount - whatever the consequences for innocent drivers caught in police traps by faulty readings.
