Old School

Nothing digital for the engineers to analyze.  Nothing adjustable for the mechanics to tweak.  No radio strategizing with the team manager.  No spotters in your ear, either.  Plain old incandescent bulbs in the headlight buckets.  Your job, if you were lucky enough to have it, was to get in a drive for 3-hour shifts. If it rained, you got wet.  Maybe an extra pair of goggles around your neck.  "Deal with it," as we say nowadays.
