Heading eastbound on California Avenue, east of CalTech before entering San Marino. Usually a pair of motorcycle cops, parked on the south side of California on S. Sierra Bonita Avenue or Landor Lane armed with LIDAR (very difficult to detect on my Passport 8500). They will often stand in the middle of the street pulling over often 2 vehicles at a time. 30 mph speed limit, but traffic here usually travels at 40 mph.
