Similar? Based on same principles? Yes. Massively similar? No! You're either playing the fool here or you actually believe what you're saying. Yes, a Veyron and a Model T are both motor vehicles, but saying they're massively similar is ludicrous. The ~100 years of development that's gone into several major components in modern cars (all modern cars, not just the super-expensive ones) puts them light years apart in terms of technology. Look at modern tyres and compare them to those of cars from ~100 years ago. They're still round and black but now you can get tyres that provide great grip for tens of thousands of miles for a small amount of money.
Yes, it does. If you could go back in time to the release of the Model T and tell Henry Ford that in a few decades we'd have cars that could aid drivers by sampling the state of the car and applying corrective measures he'd be stunned.
No, it doesn't. The Veyron was designed with a (relatively) good understanding of aerodynamics. At the time the Model T was being designed the world's understandings of aerodynamics was much more primitive. There are other key areas where the design principles are vastly different (e.g. the gearbox).
I don't know what to say to that because it's pretty ridiculous.
That isn't "changing everything" though, is it? It's bringing an existing technology to more people. Now, they're massively different.
Not all of us fall for Apple's blurb (or any other company for that matter). See my thoughts here on the marketing side.
It does if it's clearly a specious claim (like with some Apple products). Some innovative or pioneering products are still marketed heavily, of course, but Dyson claiming that their vacuum cleaner design revolutionised the market is true.
You're right, we don't know.
I've always thought marketing was one of the slimiest professions to be in. I'm glad I won't get a job there.
