Is it that easy? There's not something complicated about shifting or something?
(Remember, I'm only 36 - I've never actually had to drive a three-on-the-tree or any other kind of weird manual vehicle. Standard stick shift is the extent of my experience.)
That bus is certainly an automatic. Sadly, most buses are these days.
BTW, I'm CDL, Passenger and routinely drive 4 speed, double shift passenger buses. Not a real steep learning curve.
The way I see it, anyone with average intelligence would be able to figure out a three-on-the-tree or any other weird manual-shift vehicle with at most two stall-outs.
