"we could" means "we don't". license plates for cyclist is a populist love child, but in practice almost the license plates on cars might be of use to me as a cyclist are if they actually run me down and there are witnesses. or parking violations maybe.

otherwise it's usually a he-said-she-said situation.

note: dashcams (for cyclists) aren't legal (or at least legal gray area afaik) in my country for privacy reasons.
