Not an EV driver yet (perhaps by mid-Oct, but that is another story... buying an Air isn't a clear process, sigh)... but that said, everthing I've seen is that "trip planning" is hard, and there are entire companies that exist and do a decent job (far better than Lucid can do on its own, it has MUCH bigger fish to fry in the software area)... no, I'd rather that they hooked up with ABRP (and others) to have the car provide SOC (etc) info to those apps in real time and use those other apps' route planning in an integrated fashion...
In a way it does. ABRP allows you to customize vehicle. You can manually put in the mi/kW you have. Mine was pretty consistent on the long road trip.
