An Arrogant twatt yes, Dangerous probably, Genius driver defiantly, watched him at the Silverstone GP 90,91,92,93 and he was class of the field, Donnington in the wet was incredible.
Right up until he ran out of fuel on the last lap
The only time I think I'd disagree with the old man here, is 1990 - he had a pretty dominant car that year, and he stacked it at Silverstone about 1/3 of the way in. 92 and 93, he was ragging the absolute balls off the car, and yes, it was clear even as a 10/11/12 year old that he was a very gifted individual.
Yes, Senna tainted his name with some of his antics - no, he wasn't the ultimate champion - no he wasn't really the most dominant driver of all time - but for me, the sport (and my childhood) would have been much the poorer without him.
What I'm getting at, is that at least it was interesting - there was actually something controversial to watch. Since then, we've had what feels like a lifetime of dominance from Schumacher, interspersed with the occassional fin, spaniard or brit who could win the title - but did any of them really make you want to turn on the TV, or go to a race, to see what trick they'd try next??? No...me neither - which is why, whilst I can't say that Senna was the greatest driver to grace the track - he was at least, one of the most interesting.
