As an almost-daily bus rider, I’ve noticed that in recent months, the Port Authority has launched a wide-ranging PR campaign. Buses are now graced with little pro-transit jingles, for example. I’ve even seen Port Authority ads at Steelers games. I don’t begrudge these efforts -- much. But it’s worth making the following observation: There’s nothing worse than being told how great riding the bus is -- when the bus telling you so won’t stop to pick you up. Now you’re just being insulting, Mr. Bus Driver. You need to stop. It’s not the driver’s fault. It’s a matter of policy.
