Yes, at least partly. Payments for mileage are definitely a separate thing from regular wages, because you own your car and your boss needs to pay you for wear and tear on it. If payment for time spent driving is also mentioned in the law, that's probably on top of their regular wage, though there could be an exception for people who's job is only driving.
