Narrative:

While inbound to sql; after passing sunol and heading toward coyote hills; when approximately at imply; I noticed opposite direction traffic at my altitude on a collision course. I made a 90 degree turn to avoid the traffic. The other aircraft (a C172) did not change direction. I believe the other pilot never saw me. We probably passed within 200 feet of one another. The same day while outbound from sql and in approximately the same location; while climbing through 2500 ft; I was passed directly over head by a cirrus. Separation was less than 200 ft. The place where these incidents happened has a high concentration of traffic inbound and outbound from both sql and pao because of a gap between the hills and because it is below the bravo airspace. I believe that these incidents are representative of a serious potential for a midair collision in this area. Also; since I experienced two such incidents in one day; close calls like this must be happening regularly to other pilots. Therefore; I recommend that the FAA issue a safety advisory to bay area pilots reminding them to exercise extreme caution in this area because of highly concentrated traffic. Furthermore; a landing light should be illuminated at all times (day and night) while between sunol and sql or pao.
