As an expat Brit, I am also confused.
(Not lived there full time for a long time)
I was always an AA member.
Today, based on this post, no idea what RAC is ... but clearly NOT helpful and I would never be a member of it.
IAM (Institute of Advanced Motorists), yes or AA but not RAC. Utter gibberish.
Wonder if Tesla UK (Maidenhead) has anything to say about this?
Given petrol and diesel prices in the UK, I would think there would be even better widespread adoption of EV than in the USA.
