I've driven my Model 3 between Fort Worth and Austin via 281/183 several times, stopping at Stonegate to charge. That said, since my destination in Austin was on the far southwest section, near the Waldorf school, that meant wading through Austin traffic. Prior to my Tesla I avoided that by continuing on 281 to 71, south of Burnet. So, a supercharger in Burnet or Lampasas would be awesome, as even in a LR RWD Model 3, going that far without a charge stop is cutting it very close, and would leave me looking at Level 2 charging on that end vs. a supercharger.
