Nico Hulkenberg has admitted that he may now never return to Formula 1 and has gone on to say that the 'questionable choices' of drivers for some teams have left him without a seat in recent years.

For many, Hulkenberg was one of the most promising drivers during his time on the grid and the feeling was if he had been given a quick enough car, he could have delivered podiums and race victories.

He largely never had the chance to do that, though, and so it's apparent it will go down as an opportunity missed - though he accepts that sometimes that is Formula 1.

Reflecting on his time in the sport, ahead of a likely switch to IndyCar for next season, the German said that it is probably going to be the case he doesn't return to F1 now and that is fine, but some teams perhaps make decisions on drivers based on financials more than talent alone:

“Yeah, definitely. I’ve got to be realistic there, that this train probably has left, especially given today’s current situation," he said to motorsport.com.

“It is what it is. Obviously, as a driver, you’re part of the process of the decision, but the teams ultimately take the decisions and some teams have some questionable taste or decision-making!

“And yeah, it’s a bit of an interesting situation in F1 in general at the moment. I feel like the top 10 drivers, maybe 12, they are really high quality and real top-notch drivers. And then the bottom half, the quality is not as high as it used to be. And there is a lot of other factors in there.

“So obviously, from my point of view it’s a little sad and disappointing to see that, but that’s just the way it is.”

It's been an age-old problem for Formula 1 where the finances and sponsors a driver can bring to a team sometimes outweigh the ultimate talent they've got.

Certainly, you'd feel as though Hulkenberg still has a lot to give in an F1 field but it appears his time in the sport has come to an end now, and he'll be eager to get as much as he can out of what comes next.
