Maybe they just want to change, it's not that they don't care.
Have you ever been through a change in your life?
A divorce, a bargain, a loss, a sudden gain, an affair, a change of mind...
These things don't make your past worthless.
They just breathe new life into the present and the future.
It's like a complete haircut: at first, your mother won't recognize you.
So instead of fossil fuel power, an English powerhorse can become a colorful and maybe seemingly pointless luxury electrical vehicle that is ready for controversy, in plain British style. A new Queen.
I like to think it this way: does the world around you actually make any sense nowadays?
Is what brought us here still valid? Or do we need some radical change?
I think that when you are a company and sell luxury products in a capitalistic society, you try and do both at the same time, touching the irrational part of people, their values. They placed a bet on people who will like to think different in 10 years time - which is what new car model projects have to point at: "How do we shake the world of a rich person in 2034? Let's go in that direction.". This of course is my humble opinion, but I think it makes sense. They may as well just have failed to do that, I don't know.
