Table 2 The different measures analysed

Measure	Source	Criteria	Normal
TTC	$t_{2}$	C1, C3, C4	Yes
lateral position	$t_{2}$	C1, C3, C4	No
longitudinal speed	$t_{2}$	C1, C3, C4	Yes
steering wheel angle	$t_{3}$ , $t_{4}$	C2, C3, C4	No, No
steering wheel rate	$I_{3}$ , $I_{4}$	C2, C3, C4	No, No
SWRR (5°)	$I_{3}$ , $I_{4}$	C2, C3, C4	No, Yes

The data sources are presented in Fig. 2. The list of criteria ispresented at the end of Section 1. Normality was tested foreach variable using the Shapiro-Wilk test
