Yep Evans needs to go... were 5 episodes(well not even 5 full ones yet) he's not working, dosnt suite the position, hasnt adapted and is still the defining low point of the new top gear, he's had a ample oppeertunity.
MLB works, he works well, i was a bit iffy at first but he has settled into his role very very well, and if he can get the correct co-star will see Top Gear live on for a while.
Chris Harris, well goes without saying he's a good fit, always enjoy his features, i reckon he'd work very well along side Matt, i think when he settles in he'll do well in the studio segments despite being a little wooden at the moment.
