Come on Jum, you did bump your head. Checa had close to a 4 second lead when the bike quit running. He could have chunked a tire and brought it home. Im not sure i have ever seen a 4 second last lap charge without something happening to the leaders bike.
Then I guess you've missed the last two MotoGP races.
No not last lap, but certainly the last few laps a lead can be erased in a hurry. It also happened at Laguna last year, Pedro loosened up and almost lost the lead, and that was in fact in the final lap.
But its not what you describe above, not even close. You say 4 second lead? Are you sure you're talking about this year's race? Checa had a little over a second in race one (1.6sec) and two second lead (2 sec) in race two. His bike took a dump after 17 laps in the first race, not the last lap, and 8th lap in the second race, not exactly near the end of the race, much less the "last lap 4 sec" scenario you paint above buddy.

We can't infer gifts with any degree of certainty. How many times did the leader of a race bin it last year in GP? Let me give you a list, they call them "aliens" to be cute, and each of them did it.
No, there was no gift. (maybe if we were talking last lap, last few turns, then maybe you have a point...maybe).
