It’s been nearly a year and a half since a passenger set foot inside one of SEPTA’s Proterra buses, which cost nearly a million dollars apiece when they rolled out in 2019. Most are now gathering dust in a South Philly bus depot, riven by cracked chassis and other defects. The diesel and hybrid buses that SEPTA planned to replace with the all-electric fleet remain in service, with no timeline for the e-buses to return…
Proponents, like engineering professor Jeremy J. Michalek, director of Carnegie Mellon University’s Vehicle Electrification Group, said he worries incidents like the mysterious failure of SEPTA’s ballyhooed battery fleet will scare others away from zero-emission vehicles.
“I definitely worry about those kinds of things,” he said. “If we push too fast, too early, and the technology isn’t ready and people have bad experiences, they may be reluctant to try again. There’s only a few ways to move people around without emissions, and electric vehicles are one of them.”
