Rusted-out, high-mileage buses are pretty darn common in PA, lol. Get a running and driving bus in bad shape with an undesirable powertrain (Navistar T444E, Cummins 5.9, Allison AT545) and you've got a demo derby bus on your hands.
Assuming, judging by the number that these drivers are learners, I would suggest they are never, ever, going to pass a driving test. Regards and thanks from an 87 year old Englishman. March, 2024.
Showing your patience watching one of those school bus demos, reminds me of watching paint dry, but the local crowds LOVE those events! Hugely popular mate!!
