a couple times in a group ride I did put it on slow fade and that was nice.but we were riding around looking at Christmas lights and bikes were decorated with lights.

I was on a group ride once with both my rear lights on (mounted on rear rack, and on left seat stay) and other people requested I turn off my rack light. So I obliged. In a group I tend to run one light steady, since you can adjust the brightness down a bit on that mode.
In daytime I run that steady pulse mode on my seat stay light, and the random flash mode on the rack light.
