Narrative:
On landing roll runway 28L, first officer flying, I noticed a narrow body B757 holding on taxiway D between runways 28R and 28L. The nose of the plane was very close to the runway (estimated 10-15 ft). I immediately told the flying first officer to 'veer left' and he did so. We passed abeam the stopped aircraft approximately 35-50 ft left of centerline and exited the runway. After analyzing at the gate, we figure the wingtip of the B777 extends approximately 25 ft over the edge of a 150 ft runway. If we had not steered left of center there would have been probably 10-25 ft of overlap between my wingtip and the nose of the intruding aircraft. I reported the intrusion to the tower immediately, cleared the runway at taxiway T and proceeded to our gate. There was no damage or injuries. Before leaving the tower frequency, I heard the other pilot state that he 'may have gone a bit past the hold line' and I believe that to be true. Human factors are always involved. I believe that in spite of the number of runway intrusions, we still need to emphasize a few points about this critical safety of flight item, namely that pilots must be acutely aware of the lines (both ahead of and behind them) especially between 2 parallel runways. You must not only hold behind the line in front of you, but ensure that you don't hold too far from it and let the tail of your aircraft 'hang out' behind you beyond a (now visible) clear line. I see over and over aircraft stopped after turning off of an active runway with the tail of the aircraft not yet clear past the 'hold lines.' I think sometimes that we may emphasize something such as 'runway intrusions' without providing some constructive do's and don'ts so that everybody gets the problem, but some can't figure the answer without a bit of 'guidance.' we (the industry) could do better about airing solutions as well as hammering into the crews that we have a problem.

Title: AFTER LNDG RWY 28L AT SFO, FLT CREW OF B772 HAVE TO VEER L OF CTRLINE TO AVOID CONFLICT WITH ACR ACFT STOPPED AT TXWY D WHICH WAS ACROSS THE HOLD LINE.
Narrative: ON LNDG ROLL RWY 28L, FO FLYING, I NOTICED A NARROW BODY B757 HOLDING ON TXWY D BTWN RWYS 28R AND 28L. THE NOSE OF THE PLANE WAS VERY CLOSE TO THE RWY (ESTIMATED 10-15 FT). I IMMEDIATELY TOLD THE FLYING FO TO 'VEER L' AND HE DID SO. WE PASSED ABEAM THE STOPPED ACFT APPROX 35-50 FT L OF CTRLINE AND EXITED THE RWY. AFTER ANALYZING AT THE GATE, WE FIGURE THE WINGTIP OF THE B777 EXTENDS APPROX 25 FT OVER THE EDGE OF A 150 FT RWY. IF WE HAD NOT STEERED L OF CTR THERE WOULD HAVE BEEN PROBABLY 10-25 FT OF OVERLAP BTWN MY WINGTIP AND THE NOSE OF THE INTRUDING ACFT. I RPTED THE INTRUSION TO THE TWR IMMEDIATELY, CLRED THE RWY AT TXWY T AND PROCEEDED TO OUR GATE. THERE WAS NO DAMAGE OR INJURIES. BEFORE LEAVING THE TWR FREQ, I HEARD THE OTHER PLT STATE THAT HE 'MAY HAVE GONE A BIT PAST THE HOLD LINE' AND I BELIEVE THAT TO BE TRUE. HUMAN FACTORS ARE ALWAYS INVOLVED. I BELIEVE THAT IN SPITE OF THE NUMBER OF RWY INTRUSIONS, WE STILL NEED TO EMPHASIZE A FEW POINTS ABOUT THIS CRITICAL SAFETY OF FLT ITEM, NAMELY THAT PLTS MUST BE ACUTELY AWARE OF THE LINES (BOTH AHEAD OF AND BEHIND THEM) ESPECIALLY BTWN 2 PARALLEL RWYS. YOU MUST NOT ONLY HOLD BEHIND THE LINE IN FRONT OF YOU, BUT ENSURE THAT YOU DON'T HOLD TOO FAR FROM IT AND LET THE TAIL OF YOUR ACFT 'HANG OUT' BEHIND YOU BEYOND A (NOW VISIBLE) CLR LINE. I SEE OVER AND OVER ACFT STOPPED AFTER TURNING OFF OF AN ACTIVE RWY WITH THE TAIL OF THE ACFT NOT YET CLR PAST THE 'HOLD LINES.' I THINK SOMETIMES THAT WE MAY EMPHASIZE SOMETHING SUCH AS 'RWY INTRUSIONS' WITHOUT PROVIDING SOME CONSTRUCTIVE DO'S AND DON'TS SO THAT EVERYBODY GETS THE PROB, BUT SOME CAN'T FIGURE THE ANSWER WITHOUT A BIT OF 'GUIDANCE.' WE (THE INDUSTRY) COULD DO BETTER ABOUT AIRING SOLUTIONS AS WELL AS HAMMERING INTO THE CREWS THAT WE HAVE A PROB.
