As you all know, this season teams are allowed to use bi-directional communication. That means that data from the car is not "read only" during the race, but can be edited from the pits. Whenever the team sees that the engine-temp is going up or other problems might occur, they can change the software setup in real time.
Since we all know, at least the major teams are intercepting each other's radio anyway, so if they have a good specialist it should be no problem to crack these transfer protocolls. My fear is that this "bi-directional comm" is not only a further incapacitation of the driver but also an invitation to sabotage. I find the idea scary that Williams might be able to blow up McLaren engines whereas Dennis can switch off Montoyas traction control at will. Of course Ferrari would never think about something like this ...
REHAB IS FOR QUITTERS
