Jenson Button has said that he thinks the new offroading series Extreme E in which he is involved as a driver and team owner is even more terrifying than racing in Formula 1.
Button owns and drives for the JBXE team, which stands third in the championship after the first two races of the inaugural season, and the series has already raced to raise awareness of climate change in the deserts of Saudi Arabia and the sand dunes of Senegal.
"I'm definitely on the back foot but for me it's all about learning, I want to do stuff that is challenging," Button told Reuters.
"However scary it is, I still want to race the car.
"In an F1 car you kind of know the limits... With this thing, it can throw you through a bush. It might be OK but there might be a giant boulder on the other side. It's definitely a little bit scarier than F1."
Button's team is working in partnership with British car manufacturer Lotus, and he added that he thinks there will be an influx of companies seeking to develop their technology in the sport in the coming years.
"It has to be a fantastic playground for manufacturers to really learn and prove out their systems. And it's a fun way to do it," he said.
"It's really good for Extreme E to have a manufacturer like Lotus and I think it will attract a lot more manufacturers.
"You will see the OEMs (car manufacturers) coming to the category, whether it's next year or the year after. And it will just grow very quickly when we see that happen."
