Well, from my personal experience (and I rarely get home without meeting at least a couple of bicycles) nope, it's quite an environmental hit, actually for two reasons:
1) I have to break and accelerate, which is apparent waste of resources (let alone my time)
2) My car (heh, old VW Golf) consumes about 6.5l per 100km on average, when I'm trailing bikes it's about 10l.
Most of the time I am not alone, it quickly grows to about 5-10 cars trying to outmaneuver the bike rider.
Anecdotal evidence aside, your statement about "driving slower is more effective" is plain wrong. Most motors have a sweet spot which normally is at 2000 rpm.
