HERE IN northern California the town of Livermore has wide speed bumps on all main roads. These are much like the ones in Mexico. Believe me - if they are high enough and wide enough speeders will hit them at full speed only once. The speed bumps can not be things attached to the pavement - these just get broken up. Maybe we can all pour our own speed bumps - ha ha ha - probably not.
