Being a great bloke doesnt make him a great racing driver, he did shoot his mouth off more than once, and that is probably more due to not thinking before he speaks, but rather that, than a grid full of Raikonen ZZZzzzzzzz.....
Anyone who makes it into F1 or gets podiums at Le Mans is a good driver, not a doubt about that, but his career just doesnt sparkle like the "second best driver" in the world's CV should do.
There are now, and were during his time, far better drivers than him, I am glad he left F1, Webber has done far more for the Milton Keynes based squad than Irv the Swirve did, and for a fraction of the cost.
Quick Capsule Review: He was a second rate F1 driver with a first rate ego.
