Well, if it relies on the cars ability to find a parking spot, expect it to work about 1% of the time, which has been my experience in a year of ownership.

Yours works 1% of the time? You've a very special car then. Special, indeed! I gave up on mine. But I'm perfectly capable of parking my car on my own, so it's not really an issue as far as I'm concerned.

Yeah, 1% might be generous.

i find it works really well… with spaces that can fit 2 cars….

I'll be honest, I haven't really used it yet. How does it work for parallel parking.? Really have no use for perpendicular.

Got it primarily for the cameras, which really help in my cramped garage.
