The good thing about Texas heat is it's in Texas. And we're not. Been a long time since I've lived or ridden there, and it's not likely I'll commute there again.
If I were commuting there and couldn't lane split, I expect I drive. If the bike offered an advantage, probably wear mesh. I don't wear mesh here, and don't really get it for our conditions.
It got almost hot enough this week for me to switch out of my Roadcrafter. It did get hot enough for me to take the BMW roadster on a day I had planned to take the Africa Twin. Was hoping to get a few hundred more miles out of the front tire before I replace it...
