I’m as confused as you two are but in my case as to why it’s such a mystery? I have to believe that you both know that not everyone goes off road where lockers are necessary all day long, or even a significant portion of the day for that matter, but yet some choose to have them (me included) because invariably obstacles or trails that do require them will be mixed into the day in varying numbers by choice & voila, there they are ready to do what they were designed to do. On any given day I can roll along for a couple hours without incident then encounter an issue, reach out & hit the button, then 30 seconds later reach out & hit that button a second time having cleared the area & be on my way. That sequence may happen 2 or 12 times during the course of a full day in the mountains, it’s hard to say, but what’s not hard to say is that the selectable lockers are worth their weight in gold to me for this on/off ability. If they weren’t meant to be shut off at-will for any reason they’d all be automatics.
It’s really that simple.
