OAKLAND -- The California Highway Patrol has released recordings
of a dozen emergency calls from motorists reporting a brazen
daylight sideshow that stopped traffic and rattled drivers on
north Interstate 880 on Saturday.  The screeching of tires can
be heard in the background of some of the calls, as motorists
report that drivers were turning donuts in the middle of the
freeway, creating thick black smoke and filling the air with the
smell of burning rubber.  "There is smoke everywhere," one
caller reported on the tapes released Tuesday.  "We are stuck on
880 and people are standing on top of their calls taking
pictures," said another caller.  A dispatcher sounds unsure
she's hearing correctly as she repeats information from one
caller.  "Donuts on the freeway?" the woman asks.  "Yes, ma'am,"
the caller replies.  In releasing the calls -- from a frustrated
big rig driver, a fearful mother with three children in her car
and other motorists -- the CHP hopes those responsible for the
incident will come forward,
