Why do government not just make illegal to sell and bring these into UK?
I know plenty firms who are still cheating even though wasps are now looking for these on roadside check.
So why do government not just make illegal to sell one, to fit one and to use one?

It is illegal to fit and use one on UK roads.

Then it become much harder for people who run bent by using emulator and the people who have business to make money from installing them and making them.

Drugs are illegal, the country is rife with cannabis, cocaine, heroine. Automatic weapons are illegal, they’re in the hands of people. It is never impossible for those who are really intent on getting their hands on something. The government cannot realistically check every single inch of every single vehicle and person that comes into this country. And even if they could all the maker has to do is encase everything in resin, have a few wires coming out with a plug on the end to plug into the wiring loom and unless the government are going to test every single device that comes into this country it could be claimed to be anything. Or are you expecting the government to have someone who sits there at Felixstowe and tests a 100,000 widgets in a container that’s just arrived from China and to check and test the contents of every single one of the 20,000 containers that arrives on a ship?

I see what you say about the checking, it is very hard.

I know is illegal to use on the UK roads but I do not think it is illegal to be fitter. Because lot of companies advertise this and say they make them as well.

Strange situation when they can make the device, put the device on the truck for you and make money from this, but only illegal when you start to drive truck on the road. Not illegal to sell the device like with drugs!
