Standard argument:
Drive a little bit faster => arrive a little sooner => less cars on the road, less conjestion, less accidents.
Other than the compression waves that extend behind the guy who brakes that's true. Unfortunately, on a busy road, that effect overwhelms any benefit from speed.
Not to mention the little issue of each peiece of road being safety limited to one car per two seconds per lane even when it is flowing. Less cars overall means nothing at the choke-points.
Fine the slow coaches!
It's the people that don't leave gaps that are the problem. Typically, everyone's worried the agressive cutters are getting an unfair advantage, so refuse to leave gaps for them. No gaps for them means inefficient merging and lane changes for _everyone_, which leads to merging and turnoff points causing slow-downs.
It also compounds that compression wave problem (which don't form at all if everyone's running big enough gaps).
Even when you're crawling, even when you're jammed, you should leave enough room for a car or three to nip infront of you, or the idiot infront to brake for no reason, and each driver doing so can make a big difference. When the agressive cutters inevitably nip in, ever so gently ease up for a while to make /more/ room.
Ultimately, city roads are limited by the rate people can get off the end of them, and everyone else should drive just slow enough as not to close up with those infront as they do: so avoiding the merge-jams and compression waves that /really/ slow everyone down.
