So in other words, the 911 was amazing design. I dunno about you, but to me a car that practically drives itself sounds awesome.
I don't actually think the 911 is a good design at all. There's good engineering to make a bad design work, but it's pretty much inferior to a genuinely well designed car which doesn't require quality engineering.
The AK-47 is a better assault rifle than the AR-15, in that an illiterate dude with a stamping machine can turn out a reliable AK-47 which can be operated by children, whereas the AR-15 requires pretty high tech materials to work well (the right lubricants, the right barrel linings, etc.), and while it's easy to shoot, does require some maintenance which illiterate children aren't going to give it.
Now, the older MX-5 Miata, that's a good design. Simple, cheap, drives well.
Turns out putting your engine behind the rear axis is not a very naturally stable design. Needs computers to keep it drivable.
Of course you likely won't notice any of this driving to the supermarket ... but then you're abusing this car and should feel bad.
I bet more new drivers struggle with the heaviness of the clutch and lack of power steering before they get anywhere near the limits of the car.
Granted, the car I drive also understeers madly ... but all cheap front-wheel cars do that. (yes, I like having fun with cars even when they're cheap and have no business being driven like that)
As for the car's limits, you don't buy a car like this to not hit the limits. If you do, then you make me sad.
