I think thats one of the key factors in Schumi's relative lack of performance since coming back to F1. Think back to Schumi's early career, it wasnt until '94 when refuelling was introduced that Schumi really came to the fore (...) Ford V8 powered Benetton driven by Micheal Schumacher that won through amongst countless allegations of cheating (indeed, the car was found to have traction control software buried deep in it's ECU, along with McLaren though both claimed to use it for "testing purposes").
