It's good to admit one's mistakes.
Vince is willingly speeding down the freeway when he gets pulled over by officer Don who is about to write him a ticket.
Vince wants to convince Don he should let him go.
Vince tells Don he was an idiot for speeding and that he knows he shouldn't have done that, and he's sorry.
Vince tells Don his foot had a spasm and got stuck on the accelerator, and he couldn't get it off in time.
Don sees that Vince is genuinely remorseful and reduces the infraction on the ticket to only the most minor fine.
Don knows Vince is probably making up nonsense and gives him the maximum fine possible for being dishonest.
