My college physics professor said the same thing, and for the past thirty years, I've regretted not challenging her.
That online test measures reaction times in the absence of context. However, in the real world, we all see things in context. If there was a countdown timer or visually indicator (like seeing a car go through a straightaway and approaching a turn-in or apex), then the reaction times should drop--whether they drop significantly or by a rounding-error is a variance of the individual.
In other words, if I randomly said "Now" to prompt you to hit a button, your lag time would be much higher than if I said, "3... 2... 1... Now!"
