Drivers say they are largely unconcerned by the increased number of races being proposed for the 2016 Formula 1 World Championship season, even if they admit those with families may find the schedule more difficult.

With this in mind, drivers were quizzed on whether there should be an enforced limit to the number of races in a schedule when offset against personal lives, a question that prompted Romain Grosjean to respond by saying 'the limit would be the divorce'.

Force India drivers NIco Hulkenberg and Sergio Perez were also fairly blas? about the increase, saying they will 'do as many races as they are told'.

However, Grosjean went on to joke that increased calendar is a ruse to push out the older drivers with children, saying 'they want to get rid of the old ones, more so even those with kids!'.
