I'll be upgrading from either my 2002 Honda Civic, or if we decide to replace my wife's car before the Model ≡ arrives which is likely, I'll be replacing her 2005 Honda Civic. Luxury vehicles, I know.
She wants a Subaru Crosstrek for the increased ride height, functionality of AWD, a bit of cargo room, and still somewhat respectable mileage. Since she only commutes ~15 minutes each way, the 26/34 mileage won't hurt too badly... hell, our civics only average about 29-31 in real world driving anyway.
For me, the primary reason for choosing an electric is that since we're a 2 car urban household, at
least one all electric car just economic and environmental sense. I'd prefer two electrics, but for now my wife isn't convinced we don't need a longer range car for our hiking/outdoors trips. I'm trying to lure her into a Model S test drive so she sees just what it means to have an electric drivetrain. I suspect it'll change her outlook, based on what people say about test driving a Tesla... For myself, I'm not entirely opposed to one more ICE vehicle. I believe the costs for BEV will come down substantially in the next decade and the range will increase such that 6-8 years from now when we likely replace the crosstrek, range & cost will be low enough to justify an all electric household. Plus, since our house doesn't have the available amperage to feed two high powered chargers simultaneously, and retrofitting it would likely cost $3-5k, we can't really take that on as well right now.
My primary reason for choosing the Model ≡ specifically is because I expect it to be a better electric car than anything out there. And I think Elon Musk is one of the great visionaries of our time and he's doing some very important things. He's gone to great personal effort and taken on substantial personal risk in his efforts, and I can respect that. I believe he's 100% right in his supposition that it's way past time to upend the ICE & Energy Industries as well as the Dealership model. I don't see many people out there with the commitment or vision to actually pull that off. I'd like to support that vision, but up until now there wasn't a car I could afford from Tesla, and I don't honestly have the drive or ingenuity to contribute to it as an employee.
