At one point, that I haven't gotten to yet in my article, I was living in my VW van camper with my Amazon parrot for company and driving a cab three nights a week, sometimes four, weekends in Santa Ana. After 8 hours of dealing with drunk Mexicans who spoke no English - but they NEVER ran out on a fare - and a zillion more of them driving cars of their own, also mostly drunk, (and they couldn't drive safely sober in most cases, self-propelled transport being a rather new concept for them), finally it would all quiet down about 3 AM.
Then, I would lie accross that big Crown Victoria seat, with that really nice stereo tuned to the local jazz station, and just bliss out, barely conscious of the cab, the dispatcher occasionally breaking my reverie, softly, "Stand 12, Stand 12, Stand 11, Stand 11, Cab at 4th and Main.... Number 21, get the Numero Uno for Jose.... Check, Number 21." I would call up in my mind enormous complicated scenarios of philosophy or some technological concept, almost like a lucid dream, and everything would be clarity and peace, floating above it all.
