plug-in vehicles can save up to $1,800 in battery costs if they are equipped with self-driving functions.

Interesting predictions, autonomous plugins seem to be symbiotic, increasing driving range as well as offsetting increased battery size for safety and redundancy. If this works out for Tesla, they actually have over $4K in new revenue when they sell the autopilot feature, $2500 price plus $1800 cost reduction minus $350 extra battery. Does that make sense?
