6.5.4.�Additional�Information
"Lane�change�with�active�route�guidance"�is�designed�for�drivers�who�are�not�familiar�with�the�locality.
This�explains�why�the�vehicle�moves�in�the�direction�of�the�highway�exit�relatively�early.�The�main�aim�is
not�to�miss�any�more�exits�and�to�reach�the�exit�ramp�as�quickly�as�possible.�A�more�defensive�driving
style�is�therefore�adopted�in�this�case.
If�the�traffic�volume�is�high,�the�function�may�not�be�able�to�find�a�suitable�gap�in�the�traffic.�The�driver
then�receives�a�visual�signal�that�he�must�follow�the�route�without�assistance.
In�poor�weather�conditions,�when�snow�is�on�the�road�for�example,�there�may�be�functional�limitations
when�attempting�to�find�a�gap.
