Jenson "just barely" made it on the McLaren team this year -- they kept him hanging long after the end of last season before they finally decided to renew his contract.
McLaren's move this year to Honda engines has been pretty much an unmitigated disaster, especially for Jenson. His car has failed on him a number of times, usually very near the beginning of races. Though, the team did quite well during the last race in Hungary, with Alonso coming in 5th and Jenson 9th, if memory serves me correctly.
The bottom line of the above is that Jenson could decide to move elsewhere, given his recent career history, and that would make plenty of sense.
On the other hand, absolutely NONE of the traditional Formula One news sources are reporting anything regarding Jenson and Top Gear.
And finally, would Jenson make a good Top Gear presenter? He's certainly a personable guy, and if he is as chummy with Chris Evans as some say, perhaps he might do a fine job. On the other hand, it would make a TON of sense for Jenson to move into race commentary, as he is certainly a well-spoken guy.
In the end, I'm a general fan of Tiff Nedell's and Jason Plato's work on Fifth Gear -- they are certainly proof that race drivers can do a decent job on TV car programs.
I certainly could see the end of the Stig -- that's something that Chris Evans really doesn't need to bring forward from the CH&M Top Gear. So, fine, go ahead and have a professional race driver doing the hot comparison laps. And even that -- who says that Chris Evan's Top Gear has to have ANYTHING that went on previously? They could do away with the fastest laps and the SIARPC, just like that.
Perhaps the bottom line is that a big name like Jenson might well help the new Chris Evans Top Gear do well in the ratings, and I think we all would agree that the ratings for the new show won't be anywhere near as good as the CH&M version. So, it would make plenty of sense to have Jenson on, no doubt about it.
My bet? This is typical UK press garbage, and it'll never happen. Simple as that.
