True. It also depends on the frequency....when there's a puddle once every mile or so, maybe you ride around. When there is one every 50 feet, you start just plowing through them.I think some just like getting muddy, lol.
Wonder why he didn't just ride the middle section? Soil looks like sand or sandy loam and not clay. If so, it would have easily went through the middle without sliding off and to the side tracks. Tire tracks would suggest he didn't even try.
I generally don't stand in stop/go traffic, but there have been times where I have stood for many miles just because it keeps my knees and bum from hurting, especially on the end of a long day of riding My helmet is also quieter when in clean air flow than it is behind the windscreen.
