Since I set up for L1 and R1 to be my hot bar buttons, with L2 as my auto-run/camera adjust/etc button, I've noticed that it doesn't take much to accidentally trigger auto-run, and often seem to activate it without thinking I even pressed the button.

I actually make use of autorun at times, pointing myself in a direction, pressing autorun, and then running off to the bathroom, but honestly, accidental activation makes me wish I could remove it.

As a simple fix, could it be set to not be able to autorun while your weapon is drawn. It's dangerous to run with knives anyway.
