Dear Chairperson Nichols:
I write to express reservations about a CARB staff proposal to greatly expand the volume and nature of the information OBD systems will be required to collect and that could be retrieved by the government or third parties.
At the outset, I note existing OBD systems are highly successful. The emission systems of modern cars are extraordinarily clean. In fact, CARB states that emissions of pollutants from light-duty vehicles have been reduced by 99.7%. Given this success, why would CARB propose anything that may jeopardize this progress?
