Gregory T.wrote a review of Thule Passage - 3 Bike Strap Rack with Cradles on November 26, 2013
Familiarity: I've put it through the wringer
Fits both a 2013 Prius and 2005 Subaru Outback fairly well - the lower straps don't really seem to accomplish anything, but I haven't had any issues with the rack seeming loose.
I can only fit 2 bikes on the rack without removing front tires, but I'm convinced that all racks are that way and generally buy a rack that "fits" one more bike than I actually want to transport.
Bikes with a vertical rear shock fit well on the rack, but anything else is a little tricky. Specialized bikes are just a goddamn nightmare, but in my experience that's not the rack's fault.
Bikes tires tend to stick out from the profile of the car, not enough to worry about taking up two lanes, but it does kill gas mileage. I think the hit is less than a top rack would be, but it's about a 25 - 30% loss on the prius.
