I had my audio low... but.. it doesnt seem like she tells you where to go until the last moment? did she say the route before? even now that I am experienced on the highway.. I usually plan my lane changes well ahead of time.. having to make a sudden lane change is dangerous and the opening isnt always there..
It depends on the traffic ahead, if more space while merging then yes, but if traffic ahead and slow, then you have go with the flow. Doesn't make sense to go 70km merging while other traffic cars are going 40km due to traffic ahead.
