Should've been obvious that there have been some red flags about Piquet for 40 years. Not the best fighter though, looks like he just gave up after a couple of punches when Salazar didn't fall down.

Anyway, at least Charlie Whiting isn't around to see the sheer collapse of the Brabham legacy in front of our eyes. To be honest, Piquet was definitely someone whose luck outweighed his talents. Brabham had some dreadful pay drivers next to him, Renault had no reliability which blocked three titles from Prost with surgical precision and Williams were in turmoil due to Jones and his allies trying to screw over the faster Reutemann in '81. Then Ferrari had lost their two championship-calibre drivers due to horrific crashes so were left disarmed with the bang average René Arnoux as their lead man in '83.
Then at Williams in 1987 he drove the comfortably best and most reliable car with the very inconsistent Mansell as team mate. Senna was clearly the best driver on track that season but the Lotus just wasn't up for the job. To summarize, Piquet never won a title with more than three race wins! He won four in 1986 but that title loss of his to the much slower McLaren that Prost dragged to incredible heights sums up that he wasn't all that as a driver.
It's not really a fair scenario when you have Piquet and Senna on the same number of titles and Prost only one above Piquet because the infamous Prost/Senna pairing were just miles above Piquet as a driver. I'll give him credit for his 1990 season with Benetton, that was actually the best job he did all of his career.
Even during his career he had a very foul mouth and he hasn't exactly aged with dignity either.
