A car is tracked once it stands still (moves less than 2.0% of the frame width over 3 s). Washing starts when the first worker is next to it; drying starts when workers return after a gap of at least 5.0 s once washing has lasted 20.0 s; done after 15.0 s with no worker. "Done" is when the last worker left.
