That directly contradicts Item #1 - and has data to back it up. So it isn't a myth!
2) In item #2, they go with the classic friction formula F = µN. Unfortunately, that does not apply to tires.
Tires get a lot of their grip by penetrating the macro texture of the pavement. When pushed to an extreme, the rubber is torn off the tire - with subsequent increases in force. As a result, it is possible to get more than 1g forces.
If you read up about drag racing, you''ll find reports of well in excess of 1 g acceleration. You'll also find some skid pad testing over 1 g of regular production cars - albeit high performance cars like Corvettes.
So, the whole article seems built on an incorrect series of assumptions.
