I don’t known if its the heat or lack of greenery but everything I hear about riding bikes or motocycles in Texas just makes it sounds like there is some deep latent aggression there. I have bicycled in a bunch of states including the Southeast and never encountered anything like the stories people tell about Texas.
It has basically 0 pedestrian or bike infrastructure (at least where I was at, Irving, was that way). You have to drive everywhere otherwise you are literally in the middle of the got dang road.
The speed limits are also all high. They get up to 50 mph in as many places as possible.
It also doesn't help that they've got some of the worst road marking of any state I've been in. There were a lot of roads where it was simply unclear how many lanes were supposed to exist.
Now imagine throwing a bike into all this.
I don't think it's so much aggression as it is really really terrible infrastructure.
Also, FTR, Texans are actually pretty polite drivers (at least they were circa 2011 in Dallas area).
Open up any kind of cycling content on social media and you see droves of comment literally calling for killing cyclists. Turns out some people are just ontologically evil.
