How about Robert Kubica?
That’s a long shot. I don’t question the fact that Kubica might be able to make a full recovery at some point, or even return to F1, but doing that in a top team seems a bit unrealistic.
I find it hard to believe Kubica will be competitive again. Despite his injuries and his limited movement abilities (which might or might not improve), he has absolutely no knowledge of the modern F1 cars (which have changed a lot since 2010), of the Pirelli tyres, of DRS and he’s been away from motorsport in general for more than a year and a half now (he even stopped any contact with Boullier and the Lotus team months ago, and they’ve been the most supportive of them all). Plus, he was also still on a learning curve before his rallying accident.
It seems unlikely he’ll be able to pick up where he left off again. And even if he will eventually succed in doing so, it’s gonna take time and a lot of patience from whoever is willing to sign him. Ferrari, McLaren, Red Bull, Lotus or Mercedes can’t afford that.
The safest bet would be on Kubica making a return in rallying – IRC or WRC.
