There isn't going to be a lot of improvement in overall EV performance/capability from better motors. Existing, boring motors are already close to 100% efficient, already small, and already powerful.

Advancements here chip away at margins, its nice but nothing to get super excited about. Whereas a modest ~20% increase in energy density from batteries would be amazing. Every little bit we improve there unlocks new capabilities. Towing long distances, smaller affordable economy cars and sports cars, airplanes, etc.
