Maybe the mob I work for is an exception but startle events like a master caution approaching V1 is routinely trained in the simulator.
As is removing your hand from the thrust levers at V1.
Not being judgemental to point out that on a balanced field length T/O you ARE going off the runway if you reject after V1.
”Unsafe or unable to fly” is the get out of jail card , but it is the very last resort.
