But how does the company know that someone vomited? There aren’t smell sensors, and even if there are enough cameras to get a view of the floor, the tech for detecting spills and other issues is not really there yet. Unless you think a person is going to remotely inspect each vehicle between each ride. But that seems highly unlikely. If a company is not wanting to spend money on a driver, then they aren’t going to spend money on someone to watch the cameras at all times. The point is they don’t want to hire people at all. Just have computers that don’t have to take bathroom breaks or food breaks or have any downtime and can work in unpleasant conditions. Customer service is a big part of what drivers do, even if that doesn’t mean talking to the customers directly, just knowing how to make then comfortable, not just the driving. If it’s just the driving, then public transportation makes more sense to automate than individual cars.
