I rarely seem to benefit from watching online racing videos because I don't understand how fast drivers achieve the performance they do. (it is a failing of mine for decades) But last week I was watching a youtube vid comparing the La Ferrari, with the Porsche 918 & Mclaren P1. They drove at Portimao. I've always enjoyed that track but seemed to loose huge chunks of time navigating the last left hander before the track slowly bends back to the main straight. watching the cars clipping the same apex time after time made me realize I wasn't even looking at that spot but further up the road. The end result was a poor exit and an even worse entrance to the right-hand sweeper. Got me thinking...how do perception limited drivers like myself identify trouble spots and THEN learn lessons that extend beyond any single corner?
