We just had a trip out-of-state where we ran completely out and never got that warning once. Newest firmware version and on previous trips we'd almost get it too much as we'd arrive at the Supercharger with way more than it said we would. When we ran out last weekend we were 7.6 miles to the next scheduled Supercharger stop. The range showed 13 miles remaining when, without any warning at all, it shut down completely and gave the message that the car was shutting down and to pull someplace safe. We coasted for like a half mile but, being as we were on I70 between Colorado and Utah, there was no place to pull safely off other than the shoulder barely out of traffic. Needless to say this was VERY unexpected and rained on our parade as it set of a cascade of inept Tesla customer service that all but ruined our road trip.
