Many people leave racks on the car for longer. And checking the rack before every drive is just not what people do. Heck, people are supposed to check engine oil, light and other things and never do. A bike rack should just be solidly attached without the need to re-tighten.
IMHO, a hitch rack with platforms is the very best solution. Everything else has some shortcomings.
Except in general, that's not the way people use SeaSuckers. You buy one because you want a temporary roof rack. So you're putting it on when you head out, and then check it when you get where you're going, then take it off when you get back home. When I had mine, it was never on the car for more than a day. All racks have short comings, including a hitch rack. FWIW, I had a SeaSucker for when I needed to carry more bikes than would fit on a two-bike hitch rack.
