Strange how a driver with such an obvious claim to a top F1 team has spent 3 seasons driving cars that have little or no chance of winning in F1.
It is vital that to succeed in F1, assuming a certain level of talent, that drivers must be well connected and onside very early on in their careers. If you have to scratch around in mediocre or average machines for several years then you are in peril of your skills and motivation being squandered and becoming sidelined. The difference in the F1 careers of Vettel and Hulkenberg is startling, the former has gone from strength to strength, from memory starting off with a single BMW entry in 2007 followed by several drives with Torro Rosso, then 2008 with TR and the Monza win then straight to RBR with 4 wins and runner up in the WDC followed by 3 and now probably 4 WDCs in a row. Much of this, in my opinion, made possible by Newey designed cars.
In my opinion Nico Hulkenberg is at least as capable as Vettel but despite his many pre-F1 successes he has had to rely upon Williams, Force India and now Sauber. Is he less marketable than others, or is he unlucky that there are already three German drivers in regular F1 seats, why for instance, as others have commented, did McLaren choose the inconsistent and overly aggressive Perez instead of Nico?
Let's hope Hulkenberg gets the Lotus ride or something comparable/better soon.
