So far the only time I have come close is when trying to enter my driveway after a 10 mile commute in 85 deg, 99% humidity, 20 mph headwind. I was already going very slow due to being tired, hot and large headwind and when I went to turn there was a car coming behind me, so I had to slow down and wait. I slowed, started to unclip and had a hard time balancing and had a crazy vision of getting creamed by simply falling over in the path of an oncoming car. Now I unclip about 100 yds before the drive, while I still have plenty of speed.
