It might not be too late to save the Model 3. That being said, there looks to be an awful lot of structural metal around the trunk opening.
If I had to guess, this is another Elon Musk obession, in this case, the glass roof of the Model 3.
Everyone I've talked to has nixed their plans to buy a Model X *because* of the gullwing...er, falconwing doors. They're slow, expensive, and utterly pointless. Welcome to the first SUV that cannot run a roof rack. Ditto with narrowing the side sills of the Tesla Roadster. Or the pointless carbon fiber body panels that added thousands of dollars of cost to an already money-losing product.
I'll take a Model 3 with a metal roof and a real hatchback, please.
Otherwise, there's always the Chevy Bolt.
