Why cant you charge in Corpus Christie? only seems to be 160 miles. and just put on your flashers and hug the right lane if you need to slow down to 65; I get about 3.7 mi/kwh on highway at 70mph. While not the most convenient way to travel, seems doable with a DCFC stop in Corpus Christie (there appear to be 3 there? autonation, ed hicks and harley davidson) or long stop at L2.
