Mounted gun turrets aren't totally off the table, though I dunno about them being in CP2077. Going back as far as Cyberpunk 2020, cop cars routinely had turrets on them - particularly more armoured cop cars. Hell, even ambulances had turrets. The Night City Towing Company had turrets on their tow trucks to fend off against attackers while towing illegally parked cars. In fact, those tow trucks could complete the entire towing process without the operator ever leaving the truck!Doubtful unless they come with one.
This is NOT Mad Max, don't expect to be blasting your way thru the wastelands with your self-made "tank".
Obviously based on the infamous Austin Mini.
