Car wash flow is slightly different right? Because it is a cash heavy business - in that case the "laundering" happens through cooking the books to make the business seem more successful (with more cash inflows) than it actually has. That cash comes from some illicit activity with different parties than the car wash and slowly supplements the main income from running the legitimate business. In the turo example, unless I am misunderstanding, the drug dealer or whoever is providing an illicit service asks for payment through a car rental? And so now your customers have knowledge and participation in the laundering scheme.
