Some young guy (probably) was gunning his car down the freeway, northbound on 280; CHP had 2 cars parked on the median shoulder after the Saratoga exit, with one officer using the radar gun. He spotted the speeder and aimed the radar gun at the car. The driver must have seen the CHP (who wouldn't notice 2 cars) and slowed down. Eventually, one CHP car did pull out; I wasn't sure if he was in pursuit of the speeder or not. But the speeder had enough smarts to pull off at the next exit, on Lawrence. CHP probably didn't see him make the exit, they were too slow this time around.
