Don’t worry about the fail man, just do it again.
Are you driving your car? See if you can get someone’s soft, smooth, quiet, auto, 4 door car to do the test in…some instructors might be biased, ya know?
SHOW that you know how to drive by exaggerating everything, such as mirror-checking, a few under the speed limit and perfect stops. “Cool” instructors are rare these days, assume they will suck and don’t say anything more than you need to!
Drive like a cop is right behind you.
