This is going to become nearly impossible in Europe, it may already be in some places due to regulations restricting old vehicles due to emissions. ADAS requirements and other laws forcing manufacturers to implement all sorts of restrictions: just as an example, from 2024 on all new vehicles must implement ISA (Intelligent Speed Assist) that limits speed based on GPS and signs recognition. Anecdotal, but many cars built since mid 00s are ticking timebombs due to their endless electronics faults that will cost drivers a massive bill at some point if not multiple times over their lifespan, good luck finding those proprietary boards that have dozens different variants incompatible with each other for one single car model and have not been produced for years or decades. And if most car manufacturers are utterly incompetent at engineering lasting electronics, let's not get into software that they dedicate the least paid and most desperate SwEngs to work on. Coming to an abrupt halt from cruising speed on an highway is a common failure mode I've seen more than once dictated by insane ECUs programming, for example. I'd like to believe miniaturization and just maturity in the industry will make those sort of issues less prevalent for newer cars, but I'm not hopeful about it.
