So much for his definitive stance that he would never host Top Gear. I will definitely give this new new Top Gear the benefit of doubt, and I will watch it once it starts broadcasting. But I am not expecting it to become the success it once was.
Eh, what else could he do? If he said he wanted to host earlier people would have judged him harshly, and especially with all the hype going on.
It's a bit like if you like your friend's girlfriend: if they have just broken up, the decent thing to do is to leave it alone. However if time has passed and he's now with someone else, any reasonable person wouldn't mind you taking interest in her.
Not to mention he's getting a few millions quid in payments. I'm assuming it's a step up from what the BBC are currently paying him. And besides, it's not like he isn't interested in cars anyway.
