I've seen them, driven them, etc. I have plenty of friends that own them. They are very different from the average SUV in shape, etc.

Nobody would ever confuse them for any other SUV.

Does this still make them SUV's? I guess technically?

If other SUV makers wanted to make aerodynamic vehicles, they'd look like Model X. Still, if you see a Model X parked next to a normal car, it looks like an SUV to me.

Most people i've talked to think they are "amorphous blobs"

I see tons of them parked next to normal cars and SUVs, and to me, they look like night and day :)

Like, if you showed 1000 random people them, and asked them to identify the type of car, i'm pretty sure you wouldn't get a super-high percentage of "SUV"

But this is all just conjecture :)

Shape is not what defines SUVs

How are they different? All crossovers are designed to resemble SUVs. If you are only focusing on the exterior look n' feel, you are missing the point.
