There is a ton of infrastructure between Austin and Ft. Worth, it’s almost a contiguous city at this point. And there are no mountains in the vast majority of Texas, it’s very flat. There are a lot of chargers on that route, not sure what OP is talking about.

Austin to Ft Worth is not the route to my parents, it’s a separate drive I sometimes need to do. Yes there is good charging along that route, my point was that a hybrid could make that trip without wasting time for charging or filling up.

I totally missed that they had actually specified the route, and was just commenting on a generic one (which is why I guess it might be mountainous, definitely places in the West where you can drive >100 miles without charging infrastructure....just also not many people to visit).
