Felipe Massa believes former Formula One driver Robert Kubica should no longer take part in the World Rally Championship (WRC) because the sport is too dangerous.
Kubica's promising F1 career was tragically cut short when he suffered a serious arm injury during a rallying crash before the start of the 2011 season.
Since then, the Pole has returned to rallying at currently takes part in the elite level of the sport, WRC.
However, he is unable to return to F1 due to the after effects of his old injury. He has, though, tested a DTM car and driven the Mercedes F1 simulator.
"He's a great driver but I don't think he's doing the right thing, I don't think rallying is the right thing for him," Massa told ESPN.
"I never saw him after the accident because he never appears - he disappeared from us and I think in rallying he is risking himself. It's better for him to do DTM or a race that is part of his experience and understanding, rallying is very different for us.
"I know he is struggling with his hand to come back to Formula One, but maybe there is another championship he can do. Especially because you always see he is crashing in this race and that race, if I was him I would not be there."
Ferrari was rumoured to be interested in recruiting Kubica before his accident and Massa believes the former BWM Sauber driver would have been a good fit at Scuderia.
"I think he had all the talents to drive for Ferrari and other big teams. Maybe I was also in the fighting with him in Ferrari, so maybe it could have been possible to see him in the Ferrari afterwards, but things change. I hope the best for him because he is a very nice guy and a good driver."
Massa's former Ferrari team-mate Fernando Alonso believes Kubica could have challenged for the Drivers' Championship title had he remained in F1.
"He has shown his talent already in the years in Formula One and we also saw his talent in the previous categories, especially go karts where he was racing," Alonso said.
"He was the same generation as [Lewis] Hamilton, Nico [Rosberg], etc. and he was winning those years so he definitely had the potential to be number one. He could be here in Ferrari and it would have been a nice opportunity, but unfortunately it didn't happen and I am wishing him the best in rally or whatever he chooses."
