How much human reaction in reaction time?

Jeff Stout · 05-13-2017, 10:37 AM

Just curious on what drivers think or know the amount of time in reaction times are human and how much is car reaction. Foot brake or trans brake. So if. 500 is perfect. What if you were averaging .540 how much is human and how much car. Just curious if anyone knows.

I think Frank Hawley did some exclusive testing on this a few years ago. See if you can find his numbers.

Jeff, Sometime ago Frank Hawley did a story, I think was published in National Dragster. He studied and verified the difference between Driver and Car reaction time. He had actually set up a pretty cool device that separated the driver and car response. With that being said, I'm too old to remember the final details of the study, ( I'm lucky I even remember the study) , but car set up had a significant role in the true reaction time. Maybe somebody with access to the ND archives or Frank Hawley could help us out.

Thanks for the replies. I read the info from Frank Hawley. The Biondo story was very informative. I was asking because I raced on instant green. No yellows and was .506,.516,.540. Which made me think about what the car wad doing and what I was doing. I've run the same car at events with. 5 pro tree and had the same numbers with. 500 being perfect.

Test your reaction time:

I downloaded the practice tree from jegs. After 15 minutes of practice this morning I gained. 020 consistently. So tonight I'll practice as I'm the slowest in this heads up instant green race. So I need all the advantages I can. get

Human reaction time, of course, varies from person to person and tends to drop off in both speed and consistency with age. Significant age related reaction time loss tends to happen in the mid-sixties, though that does not seem to be the case with Jim Boudreau

.

Human reaction to visual stimulus (bulb) averages around .180. It's faster in response to touch (.155) and sound (.140). It's considered impossible for the human to react faster than .100. in modern track and field, it's considered a foul if someone moves faster than .100 from the gun.

I expect it's fair to estimate the human contribution to the overall reaction time (car plus driver) to be about .200.

How to improve it, well, is another story.

Thanks Bruce, very useful information.

I believe I attended one of your seminars at PRI a few years back. That, too, was very informative.

Maybe 20 years ago, weren't there special sunglasses being marketed that would improve your response time to certain color frequencies?
