Be surprised then.
The reason I was taught it is because the airline that ran the sim had at least two incidences where cars or planes had taxied out in front of them on the take-off roll, so they were teaching their pilots how to get the thing off the ground in a hurry.
The airline I was flying for at the time hired the sims off the other airline and we were swapping over to their procedures, so we did a little extra training on top of that.
