Mine is an important bicycling skill. I had to use that skill in earnest the morning of the day I signed up on Bikeforums. I narrowly missed getting clobbered by a mom driving a carload of kids who drove through a stop sign; she just looked at me in disgust and 'gave me the finger'. I'll never forget that incident.
Its also the second time signing up on BF. Back about 2011(?) the BF supreme leaders closed the accounts of everyone who would not verify their authenticity by submitting some formal documentation (it was a homeland security requirement?). I didn't agree with that, so lost my old account. A few months later I tried signing up again and it worked!
