I reckon that most of the demand for SUVs is driven by interior space, carying capacity, and 4WD. I bet there's opportunity in the market for an affordable EV that offers those features. The Model X is cool, but it isn't "affordable" like the Model 3.
Kia Niro EV seems pretty legit to cover those factors. Also Rav4 and Subaru Crosstrek hybrids. Ford Escape and Rav4 PHEV is coming this year. (Rav4 Prime looks dope)
Another aspect of SUVs is just the feeling of sitting "high", it's hard to let go of after you've tasted it. And personally, I think sedans are harder on my back after long drives. Also I'd speculate that SUVs kinda replace the mini-vans of previous generations since now we're having less kids (and maybe they're being less social?).
