See it from another angle: why are you so worked up over the specific limit of 60k? Because you would certainly say just the same thing, had the limit been 65k, 55k or even 30k.

You're practically demanding that the government chooses a limit to specifically include Tesla.

On the continuum of prices for electric vehicles Tesla is one of the (but not the sole) outlier. By choice. Of course chances are high that they will be excluded as long as there is any limit, no matter how that specific limit has been chosen.
