I wouldn't know about CP's transverse roads. I don't remember them. Back in the day, the main loops of both CP and PP (in Brooklyn) were open to traffic only until after the morning rush. You could skate, ride, or walk the main loop all day long until around 3:00 pm. No authority would bother a cyclist using the numerous transverse walking paths across the parks. Different times I guess. But there is this: Mayor DeBlasio is an extremely Liberal and citizen minded individual. NOW is the time to advocate hard for dedicated use of the transverse roads for cyclists and other vulnerable road users. Let the cars take the long way around! I also stand by my earlier comments. That doctor had years of good work left in him. For all we know he was "taking the lane", it doesn't sound like there is any other way to do it. That did him how much good? Treacherous is treacherous, and if the transverse cuts are as bad as I am hearing, the cure for that is remediation. Or avoidance.
