Jenson Button thinks Formula One should consider hosting shorter races in order to appeal to a younger generation of fans.
F1 races take well over an hour to complete, with a maximum time limit of two hours in the regulations. Button, the longest-serving driver on the current grid, thinks F1 should be open to making radical changes if it means staying "relevant" to a new audience.
"There will always be the diehard fans that have watched Formula One for 10, 20 years and will watch a whole grand prix, but that's not who we're after," Button said. "It's the younger fans we need to appeal to, to try and attract them to something for an hour and a half is very difficult.
"People have a short attention span. We're like kids, we can't sit down and do one thing for so long - we have to move on and do something else. I can't sit in front of the TV for an hour and a half and watch a film, I have to be active.
"It's a tough one because Formula One is Formula One, and changing that is a shame because that's the way it has always been. But we need to move with the times if we want the sport to be relevant."
Button believes a shorter format would be successful because it has been successfully implemented in other sports
"When I watch Formula One, I see a race that's exciting. Other people might look at it and say 'well there are a few overtaking moves, but in an hour and a half there is 10 minutes of action!'
"That's why I find it exciting, because when those moves happen it's amazing that driver has put everything on the line. But 10 minutes of action in an hour and a half is not enough for most people, and I can understand that.
"Short races, short sports are on the up. For example, people love sprint track and field because it's a short burst of energy. I've never watched a Tour de France stage, but I've recorded a Tour de France stage and watched the last 10 minutes.
"F1 needs to attract a younger audience, but how you go about doing that is a lot more difficult."
