yeah, well it's a long story but started about 10 years ago with 2 vehicle statute changes (pre-Brexit) to stop unauthorised use of inferior parts being used on the newer more sophisticated vehicles which rendered them unsuitable for the new type systems (like can bus electricals) that used hundreds of sensors to make it work. anything outside of the parameters of the systems used to just shut down the whole vehicle and caused many fatalities when vehicles just shut down on their own on busy roads.Sounds like a dystopian society,
of course, once the ball starts rolling downhill it never stops rolling so now any parts not listed for a particular vehicle that are not OEM stock (or an exact copy) cannot be used.
the whole parts supply chain is now geared towards this aim. not really a problem with newer vehicles in fact quite sensible just a PITA if you have a 30yo bike to keep going.
thanks for the sentiment a sad event for us all. but as we say here "the Queen is dead long live the King" but at his age we may be doing this all over again before too long.Peace and Bless the Queen.
