"I think this last part of the season has been super-intense with the travelling backwards and forwards," he said. "The amount of races is definitely at the limit, not just for the drivers but also for all the mechanics out there.
"The schedule really has to be more efficient and try to look after everyone in this world a lot more. My main concern is some of my mechanics, really.
"Obviously, it's something that we're going to raise up to try and see what can be done. Probably now is late for next year, but for the year after to really try to maximise it.
"I remember seeing people so exhausted in the last race so I think it's something that we've got to be taking very seriously.
"It's important for the sport, for the drivers to obviously keep having this long careers that we've seen from the staff, from the mechanics, we want them to have very long careers as well."
