Public release of the general problem is still worthwhile as information, but there is a net "security" loss here.
And it's not like regular people are going to turn into car thieves because this exploit has been made public. Not even house burglars will turn into car thieves. I would guess that car thieves are very specialized due to the seemingly complicated logistics behind these operations, so it's unlikely that they weren't aware of this exploit.
I'm far from being an expert on the subject, but I don't see how this is a net loss. I see very little potential for a spike in thefts and a high probability of VW finally facing the problem.
> Meanwhile VWs are still being stolen using this exploit
Holy fucking [CITATION NEEDED] batman!
the fact you weren't affected is just because stealing a car is not the hardest part of the ordeal.
And getting back to the original point: I'd want to see some coverage of how this disaster happened in the UK courts.
Hence, to answer to the question posed "So how many vulnerable cars are on the roads of the world right now because the UK High Court wanted to "protect consumers""
I would answer 'possibly zero, BECAUSE of that' and once they are manufactured and sold they exist regardless of the owner, till they are destroyed.
I merely countered the plight of old VW owners with that of new VW owners.
