[Indian Butt Magic]

But do you think he is the fastest driver in F1? He is not even in my top 7, let alone anywhere near MS.

My top 7 drivers still driving is

Vettel
Button
Massa
Alonso
Webber
Kubica
Hamilton

Easily, I rate Alonso, Massa and Kimi about the same, Hamilton & Vettel about the same speedwise as them, but lacking experience which sometimes, but rarely can cause problems, this however is of course something that they gain every season more and more, so these 5 are the clear top5 in my books with no any specific order.
Webber is good, but not that good, same goes for Kubica, and IMO Button is now good pretty much only due his car, IIRC he hasn't been showing anything too brilliant in the past (of course taking into account the fact that the car hasn't been too brilliant either, but just comparing to team mates etc)

What would be really great is to do some sort of "shoot out race" in the beginning of every season. They all have to use the same car which is being made by FIA within the F1 rules. THEN we could really see who's the fastest driver!

And I really doubt Kimi would be among the top 3.

Maybe he would, maybe he wouldn't, we'll probably never know.
The problem with this kinda race, while it would be "fair for all", is the fact that each driver has his own preference of how the car acts and fits his driving style, some like it understeering, some oversteering, some something in between, some like the ability to break late and hard, some want to take corners smoother etc etc
So building a car that favours no-one and suits everyone is pretty much mission impossible
