Signal, Mirror, Over the shoulder and Go. When making a lane change or movement to either side, one should look, not just depend on the mirrors. Yes there are blind spot detection systems in place these days but good practice and habit may still make one do a visible look to clear the are you are moving towards. I've noticed and my wife, after driving our new Sport for her first extended busy freeway/bad weather trip, noticed today that when doing the quick glance over the shoulder to check the right side blind spot, that the upward sweep of the body in the rear side windows can be very distracting, the light color contrasts with the seat and head rest colors and it almost looks like a vehicle in the window versus the body. It makes a quick glance a little "iffy" in deciding what one sees. Not sure it's significantly worse than other vehicles but we've both noticed it. I might look a little closer at maybe darkening the trim in the area. It may be that it's just different enough from our other vehicles to cause us some concern.
