In my original post, I should have said near real-time. I have updated the post to so say. Some values are not know immediately. For example, I can't determine minimum turn speed until the cay has exited the turn. In most case, the minimum speed will occur well before the car exists the turn. Most driver aids today provide feedback only after the track session has ended. And, it might days or weeks before the data is actually reviewed. Thus, providing feedback on near real-time should provide a tremendous advantage compared to traditional approaches. Thanks for your feed back Claude31.
