I doubt you'd say that if you owned one of the affected VWs.
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.
the fact you weren't affected is just because stealing a car is not the hardest part of the ordeal.
