Well, there's several minutes of my life I'll never get back ...

Was expecting a smoky burnout, some max-G cornering, or some other evil intentions.
I didn't see anything that I would consider remotely abusive. I was going to ask what the test drive was for, but I see you answered that it was a coil replacement.
As coils normally break up at higher RPM/cylinder pressure, I'd actually say that was a relatively restrained test - I'd expect to see them holding a gear (under boost) up to near redline, to make sure there was no misfiring occurring. He took it easy through the residential areas, and went far enough to get on a road with a higher speed limit for at least a bit of a test, then came right back.
I'd have no problem with seeing that footage on my car, after a similar service visit ...
