I didn't say you misread the map, I said you misinterpreted the image. Yes, it shows the final/next destination as Denver. But in a comment on the range anxiety of reaching Trinidad from Amarillo, the routing to subsequent locations is irrelevant info. IMO, that detail was unintentionally included because it was, by force, contained in the frame when capturing both the trip graph on the center screen and the driver's binnacle display in a single picture. Basically, you should have ignored it. The trip graph--showing the previous leg of their trip, i.e. Amarillo to Trinidad--shows their arrival at Trinidad was at 3%. Plus the very final bit to make it over Raton Pass even included a small drop below the original estimation, which probably provided a bit of extra concern at the time. In the other part of the original image, you can see in the binnacle that they only had 9 miles of range remaining once they got to plug in at Trinidad.
Their comment wasn't about any challenge to reach Denver from Trinidad. Thankfully, as there is and was none. Their car had 3% at the time and in the image the navigation was showing arrival to Denver, had they left at that instant, would have been at -73%. So, for their vehicle and driving conditions, it was calculating 76% as the needed charge to make it. Even with a healthy 15% margin, making it on a single charge would only have necessitated them to charge to just barely over 90% at Trinidad. Still eminently possible if a slower approach than doing the obvious and adding a charging session at Colorado Springs. Regardless, no reason for anxiety.
