Actually, all of Foster City, CA is a Speed Trap (overall they just reduced the 40mph general city speed on major arteries to 35mph hoping to justify more tickets), but this is one special intersection that routinely has police parked in out of the way places while they try to nab people. They will park in the adjacent driveways and neighboring streets hoping people do not see them, and the police will stop anyone for even the tiniest infraction of a stop sign. At times the attention to this intersection is oppressive.
