You cant compare WRC and F1 drivers they couldn`t switch classes and do well its just not possible they are totall different disciplines
Why do you think Mclaren ar struggling this year, do you think its because the PC link from the car to the laptop broke or do you think the drivers are lacking in experience and struggling to tell the engineers exactly what is happening with the car.
The telemetry can give the engineers reams and reams of data but it cannot tell the engineer what the driver requires, that comes with experience and talent, neither of which can be bought from PC world
