There is no "we". There is never a "we". There are separate legal entities.
As the company is the RK, presumably the s. 172 requirement is addressed to the company?
Ordinarily, if the addressee of the s. 172 requirement failed to name the driver, it would be prosecuted for the s. 172 offence. If that entity is a "body corporate", it cannot rely on the reasonable diligence defence unless it can show that the failure to keep records of who was driving was reasonable.
Unless you personally receive an s. 172 requirement, you could only be [successfully] prosecuted for the s. 172 offence is if they have evidence of connivance.
