Volvo already has this feature in some cars, and from my testing it appears to only work on freeways where there are clear lines to show the lanes, not just any road. As well, it only seems to do adjustments, not full on overtake, so if you&#x27;re gunning for the ditch I don&#x27;t think this feature will help much. (Although, for obvious reasons I didn&#x27;t actually try that.)
