will continue and back Felipe never mind where he ends up. He will probably go to another F1 team, but if he follows other avenues, then he will still continue to be a RM ambassador. Richard concentrates on the person, not necessarily the sport. The sport sponsorship comes through Richard's new sponsorship with Lotus. It is conceivable that next season, with Kimi moving, and a spare seat in a RM sponsored F1 team, that driver and team will both have RM backing. And given Richard's noted track record of being something of a talisman to sports ambassadors, I would not put it past the realms of probability that Felipe might yet have another crack at the world title.
Richard believes in "family" in the broadest sense. RM sports ambassadors are "family" and he will continue to back and support them if their career takes a slightly different direction.
In short, yes, Felipe will continue to be a RM sports ambassador.
