School bus start-up and drive - 2019 IC CE Cummins air brakes

I've been waiting a while for the stars to align for this one - it's a 2019 IC CE with the big 6.7L Cummins ISB, 💨💨air brakes, air ride, air DOOR💨💨, LED lights. Start-up, pre-trip, and POV drive.

It's been a few months since I've driven air brakes so I'm a little rusty, as are the brakes!
