I'm a bit surprised that .08 BAC corresponds to 70% ability. That means that in many cases, a good-but-legally-drunk driver will be vastly out-performing a terrible-but-sober driver. I'm just glad my car will drive itself soon.
>That means that in many cases, a good-but-legally-drunk driver will be vastly out-performing a terrible-but-sober driver. How do you know what percentage of ability corresponds to bad driving?
It is based on reaction time. So if you approach a stop light that turns red and you have a 70% score, you are taking approximately 30% longer to hit the car brakes.
