I own a 2015 Highlander Limited and the last car I owned before that was a 2008 Subaru WRX. Something I've really liked about the Highlander is the lighted warning of a vehicle in my blind spot on the actual side mirrors (never had this on my WRX). Is this something that is in a Model S or it seems it's only on the dash as a warning from some other threads I've read (and yet some people seem to have it?) Just wanted to get confirmation from someone that owns an MS. Would seem odd that for all the awesomeness that I've read about MS they wouldn't have lighted blind spot monitoring in the side mirrors. Is it only something in the newest MS maybe or no one?
