4. should make distinction between the one primarily used for recreation and one also used for e.g. commuting. Majority of cars are used purely for transportation and are expendable. Therefore it is reasonable to introduce a shift to electric because it has a higher impact. Track day cars are driven less miles, though slightly higher emission per mile, with smaller impact in total. It is as wasteful as operating a roller coaster in a Disneyland.
Most people don't care about what car they drive. For them driving a Prius is just fine. For petroheads driving a Prius is NOT fine. It feels as if Mac enthusiasts are forced to live forever with Windows XP, or Emacs/Vim users forced to write code with Notepad, or a mechanical keyboard user forced to live with a cheap membrane keyboard. It brings a huge disappointment to their life. For most people switching to a dull car means nothing, since they have been driving a dull car, which is not the case for them.
By the way, the more serious track day cars, without audio/AC/insurator, are painful and impossible to drive daily, in my personal experience. Especially the summer. One day I was dehydrated and could not shift properly.
