New to WRC--How should I watch and what should I watch for

[N.O.T]

Still researching, and gaining a solid understanding of this sport day by day.....In preparing for Monte Carlo, I have heard references to teams sending a passenger car out on the course to assess conditions. In Monte, specifically looking for ice/snow. Does this happen daily during any rally, or is this practice exclusive to ice/snow races?

yes their are called gravel crews, in most cases they are ex-rally drivers, all of the manufacturer teams have them and they are different for each of their drivers and some of the rich privateers also. They are used on every rally.
