i havent heard of that. i do know that they have roadside smog machines that use infared signals(sorry dont know how they do it exactly) that detects HC, CO, CO2, O2 and NOx and then will take your cars picture if you have too high of an emissions level. then they send you a letter telling you to get your car smogged. if you do get pulled over for an emissions violation(cars too loud or you are driving a honda) you have to go to a referee who will do a complete inspection and will not "let it pass for a few extra bucks" because they are employees of the state. there is legislation to end the "rolling classic" program that allows cars to be exempt once they are 30 years old. they are freezing it at cars newer than 1976. there is also legislation that will require ALL cars on the road, including historics to pass smog for 1996+ standards. the state is slowly eliminating the "basic" areas which allow a test with a BAR90 without a dyno. santa barbara shops have to use the BAR97 5 gas analyzer currently and if the city gets any bigger they will require a dyno as well.
with the introduction of OBD3 eventually the state would like to require all new cars in CA to have onboard smog machines and if they pollute more than a certain level, or if they are tampered with the state will slowly disable the car (not allow WOT, and eventually not allow the car to start) until it is fixed by an approved shop. it totally blows.
