Folks, Can you recommend any aftermarket blindspot warning system I can install on my S90D with AP1 that can work like what we find in Audi and Camry? Solid light on when someone is in your blind spot? It's not intuitive to look in your dash for blindspot warnings when changing lanes. This is a solved problem that imho Tesla doesn't solve well right now. For the premium category the cars belong to, we need side mirrors that are blindspot-aware.
