I like it when an examiner decides to step up a level or two as yours did.
I experienced that years ago when taking the flight test for my private pilots license. The examiner happened to own the company I worked for and I owned my own Cessna at the time. One section of the flight test you wear a hood so you can only see the instruments, the examiner flies for awhile doing some simple turns and climbs then hand the plane to you to level out. This time he did a full aerobatic routine and in the middle of an advanced maneuver handed me the controls. I pulled it out. After we got back to the airport the examiner says, "Never tried that before" <img src="/forums/images/graemlins/smile.gif" alt="" />

Like your examiner, he needed to raise the test level to probe your limits and rattle you a bit, we do get to remember those days.
Whomever you get to drive for, if you get sent into Baltimore or Washington DC, you will remember that test drive.
Good to see another able minded driver on the road. Congrats.
