Disruption is hard.
People buying in China are not necessarily buying it to drive, but to be driven in. Think chauffeur. So having a roomy and comfortable back seat is important. I think the model Y will be a huge hit here. When I was in China on business I was normally driven in a CUV style vehicle.
Okay, but that's not something I'd think a typical family would require, given that's what @PANN stated was the appeal for family's. Perhaps it's more a status thing? Unless family's have chauffeur's?
The main difference for long wheelbase is the leg room for the back seats. Admittedly not everyone need that or like it (less sporty), but it appeal to Chinese families.
