The former designed and built a car that cost less (each successive model year) and was far more versatile and practical than a horse and buggy, that freed people from being largely stuck where they were.

Ford did not use the power of the government to compel his rivals to subsidize his operations, as Musk has done (via the selling of what are styled "carbon credits" to other car companies, who are under regulatory duress to either build a certain number of EeeeeeeeeVeeeeees or buy "credit" – from Elon – for having built them).

The Model T was the antithesis of Tesla's cars. The latter are designed to be very high-performance and for that reason very consumptive, of both power and raw materials. They are not designed for longevity or owner-serviceability. They are operationally fragile in that extreme conditions – as of high heat and extreme cold – greatly diminish their functionality.
