Its definitely mostly for city parking. But still, people should just be able to park themselves in my opinion. It's like taking the elevator to the 3rd floor. Just take the stairs; it's faster anyway.It takes way less time for me to manually park than to go back and forth like the video and that was parking without a car on either side of that space. I can just imagine the pain you go through in order to back into a spot.
Granted I'll use it with parallel parking no matter how long it takes because I stink with parallel.
Perfecting parallel parking is a vital thing to do if you live in the city, even more so if its at night and you need to find somewhere to park.I can front or back in just fine but my parallel parking could be better. Takes me a few tries.
The parking function is useful when we get fully automated cars. For now the old school way is better.
