Assuming there is some sort of vertical frame support, I wouldn’t be concerned. The contact point with the wheels would allow for the bike to tilt slightly, enough for the vertical support to take the pressure and stabilize the bike.
I’ve had my bikes on bus mounted racks for thousands of hours and the vertical support there is only on the front wheel - doesn’t touch the frame at all. So far, damage free.
I think if I was going to get a rack for a personal vehicle, I’d want it like the bus style. No straps or clips or anything, easy one handed mounting and dismounting.
I’m a little paranoid about wheel mounted racks in general: If you have to slam on the brakes, are the wheels going to need retrued?
