It's a lot more common among SUV and wagon owners than regular car owners. The dirty secret of small SUVs and crossovers is that if you have the rear seat full of passengers, there is very little room for their luggage. Generally when you take 4 people camping you need about twice as much equipment as when you take 2 people camping, but only have about 20% the space to fit it in. The exception is really big SUVs like the Yukon XL, but for small SUVs, a sedan like a Crown Vic actually has more luggage capacity when 4 passengers are in the vehicle.
The hack to solve this is the roof rack.
I think the best solution is still a diesel SUV/pickup, and a Model S (or smaller) electric car.
I realize there are all kinds of use profiles. I know there are lots of people who buy SUV's simply because they are larger and easier to get in and out of than a car and not for the "sport" in SUV.
Tesla's claim is that this model merges the best of SUV's and minivans. That's a tall order. And the falcon doors are completely opposite that definition.
In our case, we live a reasonably active life style. Fishing, kayaking, sculling, stand-up paddle-boarding, biking, camping are typical activities for our family.
We are also into model airplanes, with some being rather large. I've been known to strap a fuselage or two to the roof rack to to flying.
I do a bit of woodworking and home improvement work. It isn't too uncommon for me to go to Home Depot and strap a bunch of lumber to the roof rack.
So, for me, when you say "SUV" and "minivan" along with "the best of both" the last thing I'd put down on the list of specs would be doors that make the roof absolutely unusable. This is what I call a Gucci SUV. One that never gets dirty and never sees sports-utility work. It's just a bigger car and a beautiful one at that.
The only way I can possibly justify getting one of these is to keep either our SUV or minivan for lugging stuff around. If I do that I might as well buy a car and benefit from better aerodynamic efficiency. I am disappointed because I was truly hoping to go all electric next year.
don't forget though, Teslas have no engine in the front... that space where the engine goes becomes a 2nd boot so you end up with more storage, even with the 3rd row of seats (obviously, you won't get a set of ski's in there but still... it's more than normal)
