Yes. My inlaws have a Traverse, and I've driven it a few times. The Matrix was worse. When we bought our Forester back in 2008, I test drove a ton of cars. I really wanted to like the Matrix, but when I brought it back to the dealer, I told the sales guy that the blind spot was too much of an issue for me. He said that he heard that from a lot of people.
I also had a rented Vibe for a week when I was out in San Jose for business. Driving that thing in Bay Area traffic was terrifying.
The only other cars that I've driven that have been that bad for blind spots were my old neighbors' Honda Insight, and a Benx C230 Kompressor hatchback.
