My two cents and I've never flown a Cirrus (Like to one day) but I did teach folks how to fly higher end piston GA planes.
The adverage pilot isn't a pro and it's the fastest thing he's flown.
You have no idea of the background (or lack there of) of the student.
These guys are flying them cross country/IMC/night/bad weather. They need to know how the avionics work. No direct only pilots allowed.
Remember JFK jr. Had he only know how to work the autopilot, maybe he'd be president.
The old "you'll figure it out as you go" doesn't work so good. Too much heads down.
