I

Interval

The time-distance between two cars. Referred to roughly in car lengths, or precisely in seconds.

L

Lapped Traffic

Cars that have completed at least one full lap less than the race leader.

Loose

(Also referred to as "free" or "oversteer.") A condition created when the back end of the vehicle wants to overtake the front end when it is either entering or exiting a turn. In qualifying mode teams walk a fine line creating a setup that "frees the vehicle up" as much as possible without causing the driver to lose control.
