RB is notoriously brutal with its drivers, then they do spend a fortune bring young drivers up through the feeder series.
I think the honey badger has a contract signed with RB till 2018, where else is he going to go? The best empty seat on the grid is the one Massa just vacated and it looks really like Williams will promote Stroll to the job next year.
The last two years the musical chairs of the drivers market is unexciting. No top seats available. Staying where he is and waiting for a spot in say Ferrari if Kimi retires or mclaren if Honda ever gets it shit together is the best he can do.
fans seem to like Kimi, Jenson, Alonso, Checo, more than erratic whiny whippersnappers like Max.
Besides, was it just last year that Bottas was the latest and greatest bees knees on the grid like Max is now, Bottas hasn't really been specatular once this year.
