As has been said elsewhere false positives of stopping suddenly are bad, but are better than false negatives of not stopping when there is something there. Also the collision-detection systems should be getting tested so that they improve too. You want your fall back systems to be more reliable than the regular system. So if you turn off the collision-detection systems never fix the false positives and false negatives then you'll always have these problems.
