I wanted to share my great recent experience with the built in navigation range estimate. During one of my recent drives my range showed 288km and the navigation said I'd arrive at my destination with 288km remaining but there was still 2.5km left until I would arrive. Lucid algo knew that the remaining 2.5km was mostly downhill so it stated that I would consume 0 km to travel 2.5kms. I arrived at my destination with 288km indeed! Great job Lucid! As others have mentioned Lucid has made great strides with their navigation algorithm
