I live right on I75 about 2-3 miles into Oklahoma, so I have the liberty of driving in both Oklahoma and Texas. The drivers in both states are completely different.
I drive in Texas 89.9% of the time. The Texas drivers in Northern Texas know how to drive...on the highway. Off the highway, it's a different story. I can't tell you how many simple rear endings at stop lights I've seen, or people getting in the wrong lanes and holding up traffic.
Now, in the part of Oklahoma I live in, it's one giant speed trap. People drive like grandma's on the highway because they're so afraid of being pulled over. And it seems like in Oklahoma, people don't know how to use the passing lane, they get in it and cruise at 60. Once you get into towns in Oklahoma, it couldn't be any smoother.
Overall, both areas aren't very accident prone, just too slow at times.
