Well I frequently take relaxing strolls in the park and have done for years, so maybe the difference is I dont have an irrational fear of bikes, and that I appreciate the space is for others to share and not just mine. I can understand there is a minority that will always spoil it, and ride too fast etc, but in all my years of using the park, I have not experienced these bike terrorists. In Dulwich park you've got those three wheeled things that kids will zip about on, weaving in and out of pedestrians; many times I've had to stop in my tracks because he/she is getting too close/is slightly out of control but I just smile and let them pass, and everythings fine:)
