Almost certainly they do have problems, but not as often as all that. According to my coworker who once worked for the City of St Thomas road works, putting in a long segment of curb is _really_ precise. They use a curb-laying machine that uses a stringline and drops the curb some exact measurement below it, accurate to however accurate the stringline is (which can be accurate to millimetres using standard survey equipment)
