I think that depends on the level of pothole you're talking about. Some in the UK now are getting so bad driving through them at any speed will damage cars. As a motorcyclist too hitting a pothole, even at low speeds, is like being punched in the chest. Hit one on a corner while leaning over or in the dark where you have very little notice could quite easily be fatal.
Having cars suffering blown tyres, cracked wheels, damaged suspension etc isn't conducive to safe motoring. There have been lots of cases of this locally in the last few years.
