I've owned an '06 Prius for 3 weeks and I'm still getting used to the back window. I've never owned a hatchback before, so the view may just start small and the spoiler makes it worse.
The only time it really bothers me is at night when there's a car behind me and its headlights are blocked by the spoiler. If I go up a slight incline, the headlights suddenly pop into view over the spoiler and I automatically look at them.
The backup camera is only useful when parking and then only for a couple of seconds.
However, the overall driving pleasure is great and I loved filling up today and paying $18 after driving 355 miles!
