As I consider a Tesla, one of my "use cases" is trips from Grapevine, TX to either Sulphur Springs or Paris, TX. We do these trips throughout the year, but very often around the holidays when it is colder, etc. I previously leased a Volt so I understand what happens with range at higher speeds, low temps, etc. The Tesla 2015 map APPEARS to show something on I30, but all I've seen reported here lately is the Denton supercharger. I hate to bank on a supercharger since it does appear Tesla can add or delete superchargers and the maps are forever optimistic. Anyway...anything?
