Besides being a daily driver it's been autocrossed and tracked plenty of times.
I have Miata friends and listen to the way they describe how tossable their cars are with a glimmer in their eye. I've driven their Miatas and I'd take my Mini's handling any day.
My current daily driver is a Model S 100D (not the P100D) and it is insanely fun to drive.
As far as daily drivers go I'd choose the Model S over the Mini 99 days out of 100.
It's over TWICE AS HEAVY as the Mini but that weight is about a foot off the ground, the suspension is more than up to the job of handling 2.5 tons, and it has a near 50/50 weight distribution.
The Mini might corner like a go kart, but the Model S corners like its on rails. I have just as much "fun" driving the Model S around town as the Mini but the effort put in to doing so is a mere fraction.
You present your Miata as a "balanced and good handling car", and I assure you; a competent electric car is 100% both of those things while also being effortless in traffic.
I grew up as a "driver" which is why the Mini is never going anywhere and other enthusiast ICE cars have made their way through my stable over the years. It's why I still choose a manual transmission car where I have to spool up the motor 1 day out of 100. And I don't foresee electric cars being realistic choices for a track day any time in the next 10-15 years.
But anybody who truly believes they aren't already sufficient for 99% of the car-buying public's needs* because they aren't "fun" either hasn't given one a shot or is in irrational denial.

Why not? People are already taking Teslas to track days, and doing quite well with them. They're faster than the majority of random cars that people are already bringing to track days. That's why track days have performance classes, so you don't have Civics competing directly against (and getting trounced by) Ferraris.
So your argument in favor of gas cars is that they are slow? Ok.
I had two Miatas, including one that I modified for autocross (SCCA CSP) and later turbo'ed. A Miata with 1.2 bar of boost is almost too much fun. Great cars! So I know what you are talking about.
About 4 years ago I leased a Chevy Spark EV, one of the most basic of tiny econo-hatches. I assume the gas one is pretty sad to drive. The electric one is brilliant. Instant silent thrust! One pedal driving! It was a revelation. I'm never going to buy another ICE car, they just don't drive right.
Try something like a Chevy Bolt or a Tesla and see for yourself.
See I drive a Miata and there is nothing like it in the electric car world. The way you zoom from corner to corner without slowing. It’s interesting that people say electric cars and fun , then quantify it by saying it’s really fast but saying nothing about the handling. The good thing about a balanced and good handling car is that you can enjoy it all the time whereas straight line speed is becoming increasing irrelevant due to traffic and zealous speeding enforcement.
Put it this way how many seconds of full throttle will get you banned?*
*in the UK where a speeding ticket of 100mph plus is a ban.
