Volvo and Renault already cap maximum speed to a 112mph while the EU regs require gps or vision based speed zone detection where the vehicle‘s speed is kept within the detected speed zone limit. In any case, the driver can override the system by pressing the accelerator with the obligatory buzzes, beeps and other annoyances. So all it will do is stop those inattentive drivers that spend social media time while behind the wheel from inadvertently speeding. Other systems will stop those same drivers from veering into another lane, etc...
The interesting bit is every time such crud is forced on manufacturers, they all complain about their silly priced performance models and how such features would render them unpopular/unsellable. Such would thus impact government income, so exemptions usually follow... Sadly, this means have the $$ to buy new upper end performance and you’ll still be able to be an idiot on public roads but the rest of us normal people just won’t get the chance
I say stop all this safety stuff and just replace airbags with deplorable metal spikes. Then, allow Darwinian theory to make the driving population smarter and our roads safer. It’s how evolutionary progress is made
