I realize my perspective is that of a motorhome driver - but the principles should carry over. What I do is using side mirrors - there is a magnification in lower, smaller section of mirrors. This lower section tells me " if I see a car there, I am safe to change lane. The back up camera ( 3 camera ? tells me the same supporting information, before I change lanes. Turn signals activate side camera - showing side along motorhome. I practiced in a parking lot where everything showed up either on camera or in mirrors and this has helped reduce Salutes. Some folks still will steal what you think is available space before you can occupy that space. Abundance of caution says practice all of the above and develope your own style. Hope this is helpful, happy camping.
