Turnip truck´s development really doesn not seem to go forward at all.
But I´m not so surprised, because they basically did not go much forward in -11 /-12, when they had Rossi. Even though failure to become competitive was a major embarrassment for both parties. Ok, they´ve got a good wet-weather racing motorcycle (though this was probably a bit by mistake, or not their aim, and they seem just as surprised about that as everyone else!)
But in general, I think they have no clue, what they should do, otherwise they would have done it years ago. Maybe not fixt the whole thing in 80 seconds, though
