For most people, the T3 will be the family car. So being able to do the practical stuff is important.
1. Hatchback and folding rear seats to pick stuff up from grocery store, HomeDepot or Ikea.
2. Kid seat latches and fit in the back seat.
Can you go to the grocery store with three kids in the backseat and put all the groceries in back. Drop the family off and go to HomeDepot for lumber to fix the deck. Hitch up the travel trailer and go camping. A family car?
It doesn't look like Tesla aimed for the family car in the T3. Tesla's glass roof obsession means no hatchback which likely means no trip to the grocery store or HomeDepot. Glass roof is also a security issue. Everything visible for thieves. Going from a Prius to a Subaru Legacy sedan, I realized how useful the hatchback and folding seats were and how the trunk only is not much use. Wish Tesla had aimed more for a family wagon vs. a smaller model S.
An actual deal breaker for me would be if the T3 did not have a trunk pass through 60/40 folding seats for skis.
Hitch up the travel trailer?? What Toyota Corolla or Camry can do that? Or BMW 3 series?
Can you not fit a bag of groceries into a regular trunk? (Okay, yeah you can't easily shove a bike or a sheet of plywood into a non-hatchback)
I just laugh when people make their list of "must haves" for a car, and either there's no vehicle that has all of them, or in order to meet them you have to go to another class of car--except that midsize sedan might be one of their must haves. Buying a car--or almost anything, for that matter--is a matter of prioritizing your list of wants/needs, and choosing the best fit because you're going to have to compromise. There's no way all the manufacturers in the whole could have enough models and options to exactly match every single person's wish list. You want best-in-class towing for a small to mid-sized sedan? I've got a pretty good feeling that the Model 3 is going to claim that title, given how well the X tows. In order to get that, you're most likely going to have to give up a hatchback trunk. The problem is that if they made it a hatchback instead to satisfy you (and many others), then the all-glass roof would not be an option, and disappoint me (and many others). So at some point you're just going to have to choose - what's more important? A hatchback, or an electric drivetrain, great towing, AutoPilot, and whatever else you like about Tesla.
And before you dismiss me as a rich Model X owner/Tesla fanboi-- I'm well aware of the compromises that I made choosing a Model X. It does
not have folding second row seats, the cargo capacity in general isn't all that great for my family, the Falcoln doors give me heartburn (I love them functionally, but scared for their long term reliability, and don't really like all the attention they draw), and even though the towing is great it's not really feasible long range without lots of stops that include unhitching and hitching back up. Oh and the price. Definitely not cheap. But then I put it up against the features I
love that are rare or non-existent from others -- all electric drivetrain with instant torque, starting each day with a full tank of energy, the amazing windshield, aesthetically pleasing (to me), the Falcoln wing doors, climate control from my phone, reduced maintenance, all of the autopilot features, the supercharger network to enable long distance travel with a pure electric vehicle, and on and on. In the end I just had to decide that I valued those enough to overlook or deal with the negatives.
So... Long story short: I really hope that you give the Model 3 a fair chance evaluating all of the factors, rather than immediately dismissing it out of hand because it has one or two features that you dislike.
