So don't buy an iCar. But if the only driving I do is to work and back and I choose that the iCar is right for me, who cares?
I don't understand this point of view, you want less choice? Maybe you miss your mommy making decisions for you?
Lotus (say) isn't saying you can't drive here or there, they just build cars that happen not to be suitable for a given activity. A passable analogy since car manufacturers have far less ongoing control might be Lotus voiding the warranty for your Elise if you took it on a rough track.
In any case, if that choice is not one you're comfortable with don't buy $PRODUCT, problem solved.
Another car analogy (which cuts both ways) I can think of is the Nissan GTR -- it has a speed limiter built in that stops you going over a certain speed on normal roads -- but then when you are on a racetrack all limits are off.
You have three choices: Buy Apple and color within the lines. Buy Apple and jailbreak, lose stability in favor of features. Buy Android.
Frankly I find it difficult to muster much outrage over Jobs' tyrannical jihad against openness (or whatever) when there are so many available alternatives. Many people are quite content with a walled garden approach; castigating Apple for taking their money seems backwards.
