As I said earlier, you can't let the lemmings dictate how fast you drive. In the city, most arterials have multiple lanes, and I stay in the right lane most of the time so faster traffic can pass me. On country roads I'll tighten my delta to 5 over the PSL down to 5 under. That makes my average almost the same as the PSL, and keeps most people happy. Traffic is usually light enough for the impatient ones to pass me. If I stack up 5 cars, I pull over and let them pass.
In my xB, 83 LOD acceleration is about average leaving a stoplight. In my SE-R, it's pretty spirited - not stoplight drag racing, but faster than most cars accelerating from a stoplight.
In terms of fuel consumption, it's about 27 mpg for 7 seconds, and 250 mpg for 15 seconds on each pulse and glide cycle at freeway speeds.
