A mammoth 18 teams appeared on the 1991 Formula 1 entry list, back in an era when it was much cheaper to own and operate a grand prix team. Of course, the caveat was that the lesser teams had to undergo the Friday morning hurdle of pre-qualifying, and had to attempt to set a time on a cold, dirty circuit to get into qualifying proper. Even then, with 30 drivers contesting the session, there was no guarantee of making it among the 26 drivers to start the race.
