Tried clipless pedals. Decided that at my age and weight, falling even once can be significant...

Moved to BMX pedals. The nubs on them hold the rubber sole for 3/4 of a turn, most often I can bring the pedal up to the 8 o'clock position when stopped, pedaling backwards.

One day, when I first started using them, I tried to get my foot of the pedal while stopping, unsuccessfully I may add, stopped, and in slow motion I fell off to the right...

...right on top of my wife and her bike...

which then proceeded, in slow motion... to tip over while she was screaming at the top of her voice...

The whole neighborhood was amused!

Thankfully it wasn't in our neighborhood!...
