As an alternative to my Drivers who Quit thread, there are a lot more who were obliged to leave F1 mid-season, often before they felt they were ready to bow out, but never got into an F1 car again Red Bull have certainly been busy in this department over the last few years but there have been many more through history. I'll kick you off with a few who spring to my mind.
Jan Magnussen - Father of Kevin, Jan did one race for McLaren in 1995 before signing up for his old mate Paul Stewart at Stewart Grand Prix for 1996. Jackie Stewart described Jan as "he most talented young driver to emerge since Ayrton Senna". His F1 performances didn't seem to suggest he had Senna's talent and was dropped half way through the 1998 season to be replaced by Jos Verstappen.
Pierluigi Martini - Mr Minardi, well no that was Giancarlo Minardi, but apart from one outing for Toleman in 1984 Martini spent most of his F1 career driving for Minardi. Half way through the 1995 season Minardi ran out of cash and Pierluigi was replaced by Pedro Lamy and he was never seen in an F1 car again.
Nelson Piquet jnr - Someone who had to live up to having the same name as a three times F1 World Champion, unfortunately he wasn't in the same league as his dad. Half way through the 2009 season Nelsinho was replaced at Renault by Romain Grosjean, there then followed a very unseemly spat between the Piquet family and Renault as Nelson jnr claimed he had been asked to deliberately crash at the Singapore GP in 2008. It turned out he had, it didn't get him his F1 seat back but it resulted in Flavio Briatore and Pat Symonds being given lengthy bans from the sport and Renault having to pay the Piquet family "substantial" damages and issue a formal apology for defamation.
There must be many more.
