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're gunning for the ditch I don't think this feature will help much. (Although, for obvious reasons I didn't actually try that.)
It is not the same. This is a full overtake system where the driver are supposed to not pay attention to the driving at all. What you are talking about is a driver assistant system.
