Some states make exceptions for recordings that take place for business security purposes. California does not. However, CA does make an exception for recording "in any other circumstance in which the parties to the communication may reasonably expect that the communication may be overheard or recorded." You could certainly make an argument that this douchebag might reasonably expect audio to be recorded in his company's driver's cars. Not so sure you could make that argument for the other passengers. Interestingly, Bloomberg could be sued (or prosecuted; $5000 fine) for distributing the recording if it indeed falls under CA's wiretapping laws.
