Summary of dependent variables.

Dependent Variable	Explanation
Takeover time (s) (TOT)	Time between TOR and start of manual driving
First eye on road (s) (FER)	Time between TOR and the first gaze on driving area
Decision Time (s) (DT)	Time between the first gaze on driving area and start of manual driving
Minimum Time-to-collision (s) (Min TTC)	Shortest time before crashing into lead vehicle, measured just before the lane change.
Max Deceleration (m.s−2) (MD)	Maximum value of deceleration profile measured on the period starting when level 3 function is turned off until min velocity measured.
Time-to-reach maximum deviation (s) (TMD)	Time needed to reach max lateral deviation during maneuver starting at 0.75 m from its initial position.
Time from maximum deviation to right lane position (s) (TMR)	Time elapsed since the moment of maximum deviation to return at least 0.5 m from the initial position in the right lane.
Distance from maximum deviation to right lane position (m) (DMR)	Distance covered from the moment of maximum deviation to return at least 0.5 m from the initial position in the right lane.
Speed variation (km.h−1)	Profile of speed (difference between velocity and initial velocity at TOR)
Lateral deviation (m)	Lateral distance from initial position at TOR.
