The oscillation is only part of my worry, it's that plus the amount of damage it might do on
a) the panels that the cup is attached to
b) whether the cups will hold due to the force from the bumps. We're talking about an undamped oscillation with a good 4 pounds attached to the end of a 12-15 foot pole with only two support points on the other end.

I can understand your panel worry. I do see some roof flex on some cars that I have rigged so far. I don't think there will be any permanent damage if you push the car. Once you start driving the car, it's different game.
As for the suction cups, I read that they Avenger advertised 50lbs holding power, but are actually under-rated and can hold 200lbs.. don't quote me on that, but I was able to hang on them fine. But I was hanging on the stud. Once you add leverage, the physics and calculations and different. A 4lb camera becomes more powerful the longer the pole gets.
Again, I suggest pushing.. I don't see any reason where driving is necessary.. especially 40-50kph. I understand it can be sunny out, but that's what ND filters are for.
