I love F1, but driving on a closed track (or highways, for what matters) is many orders of magnitude easier than dealing with traffic, people, bikes, other drivers, etc. BMW created this many years ago, and the car was better than most drivers already. Advancing track days doesn't really help much on bringing cars to cities.
I read that 4 years ago, spent another 4 months reading the listed studies, convinced myself it was a good plan, and lost 40 pounds with no exercises. I still do LCHF after all these years, and likely will never go back to a traditional diet, it feels great.
