Plenty of people have removed/blocked off the DPF on their older diesel car - now its illegal to drive (although I imagine most won't be aware of that)
The m1 north from where I live looks like it might become 60mph. Govt won't ban cars (at least not until they've cracked self driving ones), just like they won't ban smoking or drinking due to the revenue it brings in. But it could introduce further limits on cycling.
They could force all electric assisted bikes to have insurance, or riders must have a licence, ban imports of motors capable of producing 251w or more. As with my example of quadcopters we're already banned from going more than 120m up and line of sight out (despite FPV and range of 2 miles), and we might have to register our drones and carry a serial code if it's over 250g, and get a proper flight licence costing thousands of we want to fly something approaching decent and generally kill off the industry.
Will it stop the people who fly over airports or over groups of people? No, will just affect those who follow the rules.
It will be just a matter of time.
