That's interesting...and you've found it to be effective for parking? I tried and tried to use it but I find I park faster and more accurately than it can. I've had to stop it several times from hitting the curb and scratching up my rims...so I never use the auto-park features anymore.
But to me, all these 'nice', 'cool' features don't justify the price tag. Of course, like you said, some are willing to cough it up to have it, and be an early adopter.
The first 'adaptive cruise controls' cost nearly $3000 when they came out. Now many manufacturers include this option free. I would never had paid $3000 for an option like that.
But just as Tesla is charging $5000 right now, I have to believe this will come down soon as more and more manufacturers start including it.
