I don't really know what to suggest...

I sometimes have thoughts about taking my d-lock to headlights and windows, I wouldn't actually do it mind...
I guess what I would do is head to some canal tow paths and go for a slow pootle, I like to ride on my own, but that is me.
Perhaps you could find some friends and make a run on some pubs on the bike
I haven't had anyone shout at me while on the Lee Valley Way on the canal tow path...
Expect once, it is the only small tarmaced section for cars, and is narrow, which means its a pain for both walkers and cyclists when cars come down there.
A chap in a white van called me a "self-gratification artist" because I held my line and refused to be barged into the gutter by him...
Everyone else was either very nice, or said thanks, but in the colder weather I think you tend to get the more sensible people out on the paths.
When I did come up to people walking in the middle of the tow path chatting I did make a little game out of it.
I would see how close and quietly I could ride behind them and for how long I could do so, got quite good at it, and of course when they did finally see me they were quite apologetic, which of course made me smile as they didn't really need to apologise.
Other people I just said "Afternoon" to and they would let me by.
