This is my first car with the ultrasonic parking sensors; they're nice to have for sure. I won't know the corners of the car as well, but, frankly, today's cars are getting harder than ever to see out of anyway, so likely I never would have been as comfortable in a new car.
Also, part of "knowing the corners" of your car implies at least some gentle contact at some point in time, which it's best to avoid entirely.
One of my favorite features so far is rear assist, which is able to detect oncoming cars as I'm backing out of a parking spot. The bigger the car the more useful this is. It doesn't tell you when you're 6" from a vehicle, it tells you when there's a vehicle traveling at speed further away that you're about to back towards.
