@jagolevert @ajokay Maybe it depends on how long the F1 refugee has been away from F1. McNish is one of the friendliest and chattiest (if not THE friendliest) drivers and Heidfeld was OK when I spoke to him at Sebring. However, Lucas de Grassi put on his sunglasses and spent his time doodling on a picture of Tom Kristensen and ignored the fans who were in line – only signed stuff when explicitly asked to.
I mentioned this to a lady who oversees the SRT ALMS program and she concurred based on her experience with the drivers. Her reasoning for this is that in F1, fan interaction is treated as an annoying contractual obligation by FOM and the teams, hence the drivers in turn develop a negative attitude towards the fans. On the other hand, sportscar/endurance racing is a sport in which both the teams and the governing bodies encourage fan access/interaction, so F1 drivers who move to sportscar racing need time to adjust to the different dynamics.
