How fast can you react to the stop sign?

https://www.justpark.com/creative/reaction-time-test/

Got this link from an 83 year old ex-Alfisti this morning who got a response time of a 56 year old. I got response time of a 29 year old because I still am an Active Alfisti!

What can you do?

I'm 37.

I'm 59 based on my first attempt. Then 38, and finally 18.

60, then 50 then 45 then 33.....

Only the first try really gives you any indication. The brain learns the game very quickly and then you're just testing pure reaction time to an anticipated decision. Whack a mole with only one mole.

Interestingly, in the real World the old slow guy stops more rapidly because of the effect of experience. Reaction time slows with age but ability to anticipate improves.

By far the longest dead time is actually the decision making time. 1.5 to 2.0 valuable seconds are lost while the brain processes the input and decides on an output. If you are already prepared for the precise decision called for then you will achieve the illusion that your age is less! Interestingly, this is currently why human drivers outperform automated drivers. Somewhat ironically, this is because the other drivers on the road are human and not automated.

This is the technical ergonomic reason behind automated braking. People report being saved by these systems but the real difference is the decision processing time. Experienced drivers who are situationally alert do not need automated braking.

Actual reaction time, the time between output processing and actual muscle reaction is around 0.75 seconds.

Then there's the distance between the accelerator and brake pedals and the brake pedal stroke. This is why racers use left foot braking. The number 2 braking error, besides failure to decide correctly in a timely way, is failure to apply the brakes hard enough early enough. Again, experience beats reaction time and computer applied brakes using full ABS pressure beat all but the very quickest humans. Probably emergency brake assist is the cheapest most effective active safety option invented so far. Sadly our Alfa's were built before this valuable software was developed.

Pretty much baloney IMO. More internet pollution. I think it depends more on what kind of mouse and how you hold the mouse more than anything else.

OK, I might as well just throw in the towel. I think I have good reactions, but I got a reading of 86 the first time, and then just "you are a very, very, old person!" after that! Can I blame it on my internet speed?

Gets better as you keep trying, down to a general time/age. Roadtrip is correct, though that it generally gets better as you begin to concentrate on waiting for the stop sign. In real life, however, ...

Although, did have one occurrence, when making a left turn at an intersection, as I rounded the turn, a car in line in the left hand turn lane at my left decided to make a u turn right in front of me. The instant I saw him move, hit the brakes without having time to think, stopping in such a short time, Barb just said, wow. I was surprised as well.
