This one is actually not a pissing contest, or anger, or me getting screwed somehow like google and amazon usually are. This is me realizing I just got put into a discount program that is possibly setting me up for failure.
Progressive now has this snapshot program. Stick a module into your dataport on your car, and for 30 days they collect stuff. Basically hard-brakes and trip duration and distance. Meh, whatever, except, i cant avoid hard braking.
I have an issue with the SnapShot program and how the Hard Brake data is a no-win situation.
I will use math to explain my concern. This is not a whiney customer who has lost a discount, since I have not yet completed the program. I just am a data geek who noticed a catch-22. I understand that the math of how progressive actually calculates discounts is not quite this simple, but the definition of a hard brake, provided by progressive, is simple. How they are used, and what constitutes numbers that justify a penalty of course is not known by me, though I would love to know.
Item: Hard Braking is defined by you as reduction of speed of more than 7 mph/second.
Problem: The main road I drive is a 50mph road with traffic lights. The lights have a 4 second yellow light duration. That means that if the light turns yellow on me, I have as little as 4 seconds to stop. At 50mph that could be as little as 293 feet (0.0555 miles).
Answer:
I can't win. First extreme would be the light turning yellow when I am 4 seconds away, meaning, 0.0555 miles. This is an easy one to understand, since I would immediately brake, and ignoring the delay of reaction time, I would have to brake at a rate of -12.5mph/s.
The other extreme to look at is how far away i have to be, and how long I have to take to slow down to not be considered a hard brake. In order to not be a hard brake, I have to begin braking just over 7 seconds (actually 7.15 to be under) from the intersection. In case you missed the really important piece of info about this... I have to be psychic to "pass your test". I have to begin braking 3.15 seconds BEFORE the light even turns yellow.
So again, just to make it clear. I have 7.15 seconds to slow down from 50mph to 0mph, and not be considered hard braking. The traffic light is yellow for only 4 seconds. I need to start braking 3.15 seconds before the light turns yellow, not red, yellow, meaning it is still green.
