My mom just bought a Prius Prime, a plug-in hybrid, a few months ago, and it seems to solve all the problems of dealing with poor charging infrastructure in Texas. It can go around 25 miles on pure electric power, so that takes care of 90% of her driving (charging at home at night). For longer drives, it's a hybrid, so it still has a gas tank and can go just as far as a regular hybrid or gas car.
