Robert Kubica insists he will only return to Formula One if he has the ability to do so at the very highest level, saying the good news story surrounding his comeback would count for nothing without on-track results to back it up.
Kubica tested for Williams in Abu Dhabi this week as part of an ongoing assessment of his ability by the team. He is in the running for Williams' second 2018 race seat alongside Lance Stroll, but senior staff are remaining tight lipped about his chances.
The 32-year-old Polish driver last raced in F1 in 2010 before sustaining severe arm injuries in a rallying accident ahead of the 2011 season.
