Rider did 5 quick circles in front of me

Was riding yesterday and saw a rider do 3 to 5 very quick circles in the road in front of me. Can’t remember if he then stopped, turned around or just kept riding. Didn’t cause any real disruption – just wanted to pass this info along.

Maybe he was the same guy who did that on my ride this morning. It looked pretty crazy. I never caught his name.

Something like this gets posted about 3 times per day. A brief scan of these forums will reveal that this is related to either a bad network connection or sub-par graphics card by that rider.
