Technically it is safer to abide by the laws of the road that apply to cars. Does that mean there aren't certain circumstances that should allow one to go through a stop? A stop sign out in the country with full view in both directions for a long ways is fine, but not in the city, things happen too fast in the city and I've seen cyclists almost get hit from going through stop signs. The problem with allowing cyclists to run stops is that discretion as to when it is safe to run it comes down patience or lack there of! And it is usually the lack there of that most cyclists express at stops and run out in front of cars, so in light of impatient cyclists safety they should stop for all stops just as cars do.
