I don't think it's most times. It's writer based and inversely logical.
That is, if Flash wants to accomplish a high speed operating task, one that forces lots of starts, stops, turns, and reversals- such as building an entire bridge, disassembling a car, evacuating buildings or cities, or rebuilding entire towns- then Flash is free from the constraints of acceleration... but comic book writers- the poor scientists that they are- tend to force Flash to accelerate only if he's moving in a mosty straight-line over long distances, or travelling speed (this is the inverse of most characters with a FTL power-subset).
There are two factors in play:
- The first is that we tend towards consistent high showings of which there are enough instant acceleration examples.
- Even if we accept both types as showings as the rule, which is more relevant? Operational speeds, IMO, are immediately more relevant to a fight than travelling speeds, so Flash should have the acceleration default to that method of motion.
