In Formula One, Rindt had several friendly relationships with other drivers, most notably Jackie Stewart. They met at a Formula Two event in 1964 and soon became friends, often going on holiday together and living near each other in Switzerland. Until his death, they were sometimes accompanied by Jim Clark. Rindt became involved in Stewart's fight for increased safety in Formula One, being one of the leading figures of the GPDA. For his role in the safety campaign, Rindt was criticised by fellow drivers and the press alike; reporters derogatively called Stewart, Rindt and Joakim Bonnier the "Geneva connection", due to their residence in Switzerland. Stewart said that it took Rindt some time to understand the graveness of the situation but after that, he was a "good ally". After Rindt's death, his wife Nina stayed close with the Stewarts and can be seen visiting them at the 1971 Monaco Grand Prix in the Roman Polanski-produced film "Weekend of a Champion".
