The example seems a bit contrived and exaggerated. I don't think many people see things that way. A car with a suboptimally-tuned engine isn't equivalent to a car with a smashed windshield. The latter isn't even legal to drive.
Also, thanks to the internet, you can know exactly the power output of the specific model and trim (perhaps even the specific vehicle) you'll be buying before you even step foot onto a lot.
And yes you can know these things before you buy, though with modern TOS, there's no saying they can't change the terms and further downgrade your performance unless you pay up. My point is they shouldn't be allowed to do any of this in the first place. If its in the car you bought, you should have access to it.
Put another way, they aren't tuning your car for you, and that's okay, because you never knew your 110 power car was even capable of putting out 150 if you tuned it. You looked up the specific car you were buying online, saw it was listed as having 110, and thus expected it to have 110 the whole time. Then, you drove it, felt 110, were happy with 110, and bought it. No surprises there.

Sure, just like anybody selling you a car can later come and smash it and beat you up and take your wallet and steal your identity etc etc. None of those things seem to actually be happening though?

Why not? Your viewpoint is fair and valid, but all you've shared so far in support of it is an analogy that doesn't fit and repeating that you don't think things should be this way.
'Do you want to pay extra for the non-cracked windsheild?
'But the cars on the lot all look fine, no cracks'
'Unless you pay us $100, we will smash your windshield with a hammer before giving it to you. You also have to pay that $100 every month from now on, else the TOS says we can come to your house and smash your windshield. This has been shown to maximize our profits.'
