INTERESTING that you would know if someone in another car got "nailed".... most likely that person only received a warning if he or she was moving at 10-over traffic flow. This is a dangerous area- a motorcycle cop was killed just last year heading north on the 163 just north of I-8. I doubt very much that this stretch of road is being used by stationary two-wheelers as a "speed trap".... Speeding up steeper hills on interstates in California (or anywhere, for that matter) is risky- there are often slow-moving big rigs on the these grades and the CHP just won't tolerate it- they've had to scrape speeders (and their vehicles) off the pavement after they have struck and "gone under" heavy trailers way too often. Please obey local speed laws driving in California- this is not Nevada or Montana....

SR163 North does not 'merge' with 805- there is an exit for 805 North- a bit north of there, SR163 merges with Northbound I-15....
