The real problem with turrets is that when in a lab or military bunker or whatnot, opening a door can be instantly fatal with no real way of knowing that there is full auto death on the other side...
Open the door from the side and use 'x' to peek around the corner, it'll save your life since you're less likely to get hit and the turret gets less shots off at you.
But doing that for EVERY. SINGLE. DOOR... ugh, its kinda a death by boredom thing.
Actually, I found a good way of dealing with turrets: First, have some way to see at night. Without you carrying light sources, they can't instasnipe you from the doorway. Second, just throw everything made of metal you have on you at them until they die. Suddenly, all that inventory space dedicated to wrenches, bolt cutters, hammers, welders, and other assorted tools is put to good use. Plus there are usually dissector rooms FULL of metal sharp things good for throwing nearby. This worked especially well since the character I usually do that with had absurd throwing skill from tossing hundreds of units of firewood into his firepit from the next square over. With lesser throwing skill, your mileage may vary.
^This might not work against military turrets as I haven't encountered those yet and they may be more dangerous.
I finally mostly finished making my awesome mobile base supercar with welding, forging, cooking, chemistry and storage units. Then it came time to replace the gas tanks. I realized only then, that there were no gas stations on my map. Not a problem, I thought, lets just use ELECTRIC power. After all, its better for the environment! So I scrounge up an electric motor, a storage battery and a solar panel. ONE solar panel. Couldn't find the parts for more. Then I realize something else: Solar panels only charge when its sunny. And when they're within your reality bubble. And when the blue moon is out. That wouldn't be much of a problem if it was right next to my base so I could move into it full time. Spending time sleeping in it during the daytime would probably charge it up fine. But its not next to my shelter. Its all the way over in the town. I could drive it to the shelter and transfer all my stuff to it. But I need electric power for that. And I'm basically out of batteries to jump start the process. Turns out using only a makeshift welder to refit and refurbish an entire car will do that. I've raided every hotplate, radio, flashlight and aluminum can in the whole town and science lab for batteries. So I'm going to have to wait next to the car on a sunny day until its got enough juice to be drivable. Which is boring. Bluh.
