Sounds like a great feature , wish I had that on my 2014. Blind spots left and right are an issue with interstate driving. Easily managed but also easily messed up if tired and careless.
Don't wanna get too dependent on technology though. In Florida there are the race drivers who weave in and out of lanes going 20 miles faster than traffic and appear out of a blind spot of the cars behind you out of nowhere
If autonomous driving ever takes hold, that will be one safety improvement. To get those idiot human drivers out from behind the wheel
