A Field Guide to the Perfect Nap
Oftentimes we read plans by overzealous trippers to drive long hours to "get it all in" on their allotted vacation time. Every time a veteran road tripper will advise, "Don't do it."
What about those times in whichyou really do need to fit in a long day of driving? The Wall Street Journalhas a helpful article on taking naps.

As you will read, how long of a nap you should take depends on what you need to accomplish. A power nap to get you another hour safely down the road? 10 to 15 minutes. Another 4 hours of driving until you bunk down for the night? Better make it 90 minutes.
Does it apply to taxi drivers as well?
Taxi drivers still typically do 12 hour shifts (at least they do in Oz), though they do not cover the distances during that time. However, in cities, all the driving is in city traffic.
When I was driving taxis I drove from 1500 hrs to 0400 hrs next morning. During that time I would cover some 350 - 400 kms. We were told to take 'power naps' (20 mins) between jobs to stay alert. Three shifts a week would leave me absolutely exhausted. I did that for a couple of years... and yes, had a couple of minor mishaps during that time.
