He lied about:
Being sides wiped
Having a cooked gun put to his forehead
The timeline
I am not familiar with this statement from him. Do you have a source that he said he was "sideswiped"?
But I will point out that my earlier point holds. A man that has been drinking all night may not realize that he hasn't been "pulled over" when he is forced to get out of a cab he is in. Perhaps someone banging on their cab windows could have been interpreted by his "drunk @$$ as being "sideswiped."
Having a cooked gun put to his forehead
I have no doubt that part is absolutely true. The video show them on the ground with their hands up, and the woman witness linked in this thread says that happened.
The timeline
What deviation of the timeline do you characterize as a "lie"?
So far you've got a pretty weak anchor on which to support the assertion that the athletes are lying.
A more credible position is that drunk people are fuzzy and their narrative of what happened tends to reflect their own fuzziness.
No one of the others claim the gun was pointed at them. Soooo maybe it was him in the car that the gun was pointed at. Was it cocked? No proof it was not.
The video tape and news account by ABC News now say that the account given by the swimmers may be substantially correct
But it really no longer matters does it? They pay the fine, say they are sorry, move on. People not interested in truth anymore, are they?
