I can't justify spending the money on a new car when mine works, but the absolute number one selling point is self-driving capabilites. I drove a Chevy with SuperCruise, and it's a revelation. Best feature imaginable.
Eating up highway miles with minimal driver input makes driving so much less taxing. Driving in stop-and-go traffic is the worst part of my daily life, and completely eliminating that would be incredible.
I can't justify spending the money right now, but when my car dies this is the only thing I care about.
