I remeber reading somewhere that Niki Lauda, while he was at Ferrari, used to give his trophys away. Yet when Alain Prost dropped his into the crowd at Monza 1989, Ron Dennis was incensed, saying it wasn't his to give away.
Did Mclaren always keep the trophys? Do Ferrari let their drivers keep them now? Or is this just another example of the changing nature of the sport between the mid 70's and late 80's?
