Remember though, the BM4 is being ran because of political reasons, if it wasn't for that, there would be little to no BM4 service left. I'm leaning more towards BM1 and BM3 riders using the service compared to the 4, because if they noticed whatever ocasional riders get on that trip head down to Gerritsen Beach, they () would say "the hell to that", and just slash that BM4
Now that I realized, that first BM5 trip can also be used as an alternative to the BM2 (since it doesn't run that early). So essentially, both are shorter than the BM1-3, so it's kinda like a half-assed job on providing service to everyone along the BM segments.
Who would you be referring to when you say "political"?
