I had an excavator right outside my window digging up my old septic system and installing a new one. Constant distraction. Loud machine, lots of visuals, guys yelling in Spanish and me trying to figure out what they're saying (I know more Spanish than your average gringo but can't hold a conversation). I thought they were going to run that thing into my shop a couple times. And they nearly drove it into the pit they dug.
I didn't commit any serious errors (no crashes, etc) but I did habitually lose track of how much I had bored out and have to keep measuring which wasted a lot of time.
