Any companies which still trust the driver over tech (& don't micro-manage)?

The trucking companies are not installing driver cameras because the want to micromanage everything, in most cases. Their insurance provider gives them a price to insure the company operations with driver cameras and another much higher price without driver cams. The insurance cost per truck can be $20,000 per year, or higher. Who knows how much that costs changes because of driver cams. It will not be some negligible amount. It will some thousands of dollars PER truck. When you start paying thousands of dollars to fix people's mistakes you will appreciate the position of the trucking company. Your employer exists to make money, not fix your problems. Ask your employer how much it costs to insure a truck & what the price difference is with/without driver cams. It's not a small amount of money. I've made almost every mistake you can make in trucking except traffic accident or dropping a trailer in a public road. There is nothing wrong with setting professional standards and you don't have to be perfect to expect people to meet them.

P.S your company & DOT don't care WHAT you use your phone for while driving. It doesn't matter if you listen to chanting monks sing or 4-letter word comedy. If you violate the DOT regs it's a viloation. You can be fined $2500 & your company can be fined $10,00 or more. There is not DOT exception for manipulating your phone to check on traffic problems versus watching TikTok challenges. You can legally have that stuff running on your phone but DOT says "one touch allowed". I gave you a solution in a previous reply if you wanted to better get away with breaking the DOT regs. The wotld exists how it exists. You can bang your head against the brick wall until it changes or live between the brick walls as they are. Ask any toddler, how effective is it to say "the rules aren't fair" in changing the rules. Having an excuse is NOT the same as following the rules.

 

If you have a bit of liberty about camera placement, you can limit what gets reflected off your windshield.

There is a pyramid-shaped region behind a forward-facing camera which is not visible through reflections due to reflections being blocked by the camera (or any larger object behind the camera). You can get a rough estimate where it is by tracing a line perpendicular to your windshield to the center of the camera lens, then using the intersected spot on your windshield as a reference point. Places in the truck where the intersected spot appears behind the middle part of camera (or other obstruction behind camera) are not going to show in reflections off the windshield. It is not an exact estimate - the edges of the camera "shadow" will still show in reflections (and window curvature will have a minor effect).

That said, if your dash cam gets taken for evidence and investigators are strongly motivated to do so, (or if you are in the habit of posting videos on the Internet), forensic analysis can get a picture of your cab from just about any reflective object in the camera's view - mainly mirrors & glossy surfaces on nearby vehicles and droplets of water on your hood. It might not seem like there is much available if you just zoom in, but a detailed picture can be derived by combining reflections from different objects and from different frames.
