> What about a plumbing business which dispatches jobs within a 5 mile radius. If the employee moves 2 hours away, suddenly the company has to pay 4 hours a day of commuting.

As you say, if the company has a fixed office at the centre of that radius, they can still tell the worker that their days begin when they arrive at the office, and then the 'worktime' begins once they get there, ready to travel out to the first customer. That's how many businesses operate anyway — and how the business at the centre of this case used to work. The case was brought once they closed that office down.
