So flip the top two on my list.
Anything he did with the engine influenced cars of the past - no part of that is useful for future cars, but obviously it did influence cars, so we'll give him points for it. The frame stuff, though I don't think Tesla uses it, I see no reason it couldn't be influential for other companies.
Musk changed:
1 - Auto buying (goodbye forever dealers. Nobody will ever miss you.)
2 - Auto fueling (goodbye gas.)
3 - Auto maintenance
4 - Auto dashboards
5 - Autopilot. Whereas Google is endlessly in the news about their tests on self driving cars, Tesla simply makes and sells autonomous cars. It's great that Google wants to make something better, but the thing is, betas never end and products never ship at Google. Google doesn't deserve even close to the amount of attention they get. Anyways, this list says that the Google CEO should get the top spot because Google is test driving 100 self driving cars (and has been for years). Obviously Musk should get the top spot, because he has actually shipped tens (or hundreds?) of thousands of cars that manage themselves on the highway. And I wouldn't be surprised if the extra sensors that got added to the car last month will be turned on with a software update later this year that enables them to manage themselves on surface streets, too.
Respectfully, you need to look up the definition of changed. Nothing you listed qualifies. Unquestionably nothing.
1 - The overwhelmingly vast majority of people still buy cars from dealerships. Nobody will miss them because they're damn near unavoidable. Unless Musk uses some of that reservation money to bribe politicians, dealerships aren't going anywhere anytime soon.
2 - Goodbye gas. On what planet? Certainly not the 3rd rock from the sun.
3 - Maintenance? What does that even mean? All cars, Teslas included have to be maintained. Minus engine work, every Tesla has the same maintenance expectation as any other car: brakes, tires, suspension, wear n tear parts, etc.
4 - If you think the Model 3 is shipping with that single touchscreen monitor and steering wheel, well I hate to be the bearer of bad news, but: In what seems to be his favorite medium of communication, Musk tweeted that the setup shown last week is
"not the real system."
"Wait until you see the real steering controls and system for the 3," Musk said in a separate tweet,
"It feels like a spaceship."
In response to a tweet questioning the Model 3 prototype's apparent lack of a traditional gauge cluster, Musk also said
"it will make sense after part two" of the Model 3 reveal. So don't get too enamored with that interior.
5 - {sigh} The Model 3 has autonomous driving hardware. The associated mapping and algorithmic software is yet to be seen and even if it gets off the ground it's going to have to go through strenuous testing before being approved. Pretty much all car companies have the hardware.
Look I know you're a fan of Musk, Tesla, and the Model 3. I am too, well minus that nose on the Model 3. But you seem to confuse Elon's marketing and salesmanship with reality. Reality is, nothing you've mentioned has
changed. Those things could change in the future; some sooner than others. Musk is an innovator on several fronts and deserves most of his accolades. He is not a genie and doesn't sell magic carpets.
