A simulator is not going to replicate real-world track time. Ask a Ferrari driver if he would rather rack up clicks on the Fiorano test track or be in the simulator before an F1 season.
I’d bet Kimi, Vettel and Alonso all fobbed off the simulator, but had to use it for knowledge and practice. The most important part you cannot factor in are senses.
Nothing beats track time or being behind the wheel of a machine. But future drivers are sharpening skills on all fronts.
