I’m guessing precise control is nice when you need a gap of very specific height in order for the air to make a difference but not be overwhelming.

Lucky you; each to their own.

You can use it while your car is off. And like another said it’s more reliable. But obviously its a minor thing and there’s a reason new cars dont have them. Still miss it tho lol
