contd.... Removal of ETC was the reason behind Senna s death. Senna joined Williams-Renault in 94 - the one with the superior car Engine better than Senna s McLaren. Prost won it a year earlier but sensing the threat of Senna he made a strong agreement that Senna shouldn't be signed as long as he is around with Williams.
Finally Prost complained of risks to his life and retired in 94 and Senna joined Williams. It was the same year ETC was removed and both Senna/Prost opposed it sensing a great danger to the drivers and it happenned.
