Yeah, stay in front.
All seriousness aside however, what that gives you is the ability to see someone's turn signal when they are too far in front for you to see their front signal light and not far enough in front to see their rear light.
It really should be that driver's responsibility to think about what others can see. I've had people want to change lanes on a crowded and slow rush hour highway, then get ticked off because no one would let them pull in. Well, the drivers to the rear can see the turn signal and choose to be courteous or not, but drivers directly to the side can't see the request, have no way to know.
Then there are the drivers who never bother to "request" an opportunity to change lanes at all.
Actually, nowhere near all new cars have this. It's not a Federally-mandated thing like, say, backup cameras are now.One safety feature that all new cars have today are the directions on the mirrors. How did Porsche miss this on the new 718’s?
Ditto. Three of my Audis have them:-| [ rant ] They do a REALLY good job of blinding ie destroying a driver's night sight (mine) after dark while trying to reverse along an unlit public road and into my drive. All the while trying to keep safely between narrowing lines of granite 'hedges' with the style-over-substance candles they fit in the name of being reversing bulbs. To increase the rear facing illumination I have to run the hazards, rear lights, rear fogs and deftly ride the clutch and foot brake to fire up the brake lights. PAH. Really hope that Porsche's design decision for their reversing LEDs walk the walk rather than just talk the talk. [ /rant ] And, yes, my awaited CGTS is optioned with a rear facing camera.So Porsche didn't 'miss' anything. It made a design decision -- one I happen to like because I abhor side mirror-mounted signals.
