I don't want to drag this thread any further in that direction, just to say his involvement could be lacking in tact but that's similar to some other incidents his comments about Mansell & Senna etc.
Well to be fair, I don't think what he did was the worst thing ever. Flavio should have known better than to do something that would have brought out the ire of Nelson Sr given the ammunition Sr had. It is what it is though.
To be fair to Nelson, something that a few on this thread aren't being, he did have a pretty firm agreement/contract with Frank to that effect, and Sir Frank still thinks the World of Nelson to this day. Maybe he has been tactless at times, but it's only really forum-followers who have only selective media reporting that want to stick a knife into Nelson Piquet, his racing record says all that needs to be said for me, he was undeniably one of the greats for much of his career.
This is the main thing I think that gets ignored. Nelson should have been treated as a true number 1 when he went to Williams for 1986 and had that in his contract. Letting he and Nigel slug it out for that entire season was an incredibly bad idea as it was what cost Williams the Honda engines. While there are things Nelson has said over the years I did not particularly care for, he was still a hell of a driver. I miss drivers who had that kind of a personality, especially since they're PR creations most of the time now. I do think were it not for that Imola accident, his later career would have had a completely different look to it as he was making decisions based solely on finances. Not that there is anything wrong with doing that, but I wish he had not wasted his time at Lotus. If he had at least been with Benetton for 1992, that would have been rather interesting to see him against Schumacher for a full season.
