Taking a driver out for the world championship
i think it is quite a normal thing to do
Arguably prost did it to senna in 89
Senna did it to Prost in 90
Schumacher did it to hill in 94 and Villeneuve in 97
Villeneuve tried to sabotage schumachers race at suzuka 97
when it comes down to the closing stages of the year and a driver (schumacher) has a problem (damage in 94 and not a great set of tyres in 97) and the championship rival is surely going to pass and drive away with the championship, dont you expect the lead driver to make some contact to win title
consider the pressure and the effort put in to mount a championship challenge over the year to let it slip away without a fight
