IMHO Morgan use an off the shelf drivetrain that other manufacturers develop at their great expense. When pure ICE are banned, as they will be at some point, Morgan will look for the next suitable power option and build that into their cars irrespective of how many wheels it has. Or existing carbon based fuel types will disappear to be replaced by another fuel that works in an ICE but produces no environmental problems.

But to ban private ownership of transport? Don't see that happening IMHO.
