A new Model S was too rich for my blood, so I picked one up used. Great family car. Massive amounts of storage. We're out of the stroller years but it would be great with a stroller.
Even the smaller Model 3 is plenty for a 4-person family, while it doesn’t beat in liters because of ceiling height the trunk is very spacious.
So I searched Wikipedia and the types of car I was thinking about are apparently called "Compact MPV" [1]. My thinking was that these cars are mostly targeted at families, so I called them "family cars", but apparently people have different ideas what a family car is.
My point was that VW is going to end up building a large number of different EVs in the next couple of years, and Tesla will face the problem that each of their models will have to compete with 3 models from VW.
No matter what model Tesla your interested in, there will be a car from the VW group with slightly more space, and one that's cheaper, and maybe one that's a bit sportier. It's going to be very different from now, where there's very little competition to Tesla (if you want an EV)
There isn't really a great EV in that category yet, but I hope it's just a question of time.
Obviously you can use any car as a family car, but my impression is that Teslas are more targeted at commuters (except maybe the Model X, but that's so expensive that it's not really an option for any family I know).
