Senna spent his last morning chatting to former McLaren teammate Alain Prost to review the re-establishment of the Grand Prix Drivers' Association in an attempt to mend safety in Formula One. As the most senior driver, Senna was asked to take the role of leader, starting from the next race in Monaco.
In the course of the drivers' briefing, objections were raised about the use of a Porsche 911 lead car for the warm-up lap, and it was decided to abandon the practice.
