I've been wondering, do any of you guys get 'scared' that your bike rack might fall off your car? This is my one problem with me..i get so scared i ncase it falls off on the highway on the way to school, since i drive 130km. Anyone recommend a bike rack that will fit a SUV and Car? I'm leaning towards the strap ones. I don't see how those hitch ones can hold the bikes for so long since it's just something going up and out...i guess i'm kinda paranoid. Is Thule or Swagnat (?) any good?
