Drivers in this company are insane. There is absolutely no need to be weaving traffic going 100+ mph. I was on 35 and got cut off so bad I had to swerve out of the lane. I was going 85. Pretty ridiculous to be driving that recklessly and in a company truck

One of your employees in a company vehicle, cut me off and flipped me off on the exit from I-10E to De Zavala. I was just trying to get on I-10.
