I know nothing about carbon, but from what others have said, you DO NOT say that your frame is OK until it's been recertified by the manufacturer.
Many car drivers see a bike and assume it's moving so slow that they consider it a fixed object, like a pedestrian; for all practical purposes they figure you're going to be in exactly the same spot for the whole time they need to consider their actions.
An yeah, good job contradicting - if she didn't see you, how did she make a decision about how fast you were going? Good one.
