Have you actually taken any of these cars along a twisty country road? They are not at all similar.

911 is not really a roadster - it's a full on sports car. Even then the older ones top out at about a ton. Same as the Boxster and Miata.

Most serious sports EVs start at 2 tons or more. It's really impressive what they can do to hide the weight, but because it's all digitally controlled, it's really not a dynamic driving experience in the same way.

More importantly to my point - all of them have nearly identical drive characteristics. Outside of raw performance, if you put a gun to my head and asked me to describe the difference in handling between a Tesla, Mach-E, or a Polestar - I'm not sure I could give you anything.
