Paying them using time is a mistake in my opinion. Instead, we should use mileage. By using mileage instead of time, we make sure they still get paid for their commute, but also they don't get paid extra for sitting in traffic or while waiting for the bus. Setting a mileage cutoff to prevent abuse would also be a good idea, say 30 miles round trip is paid for, the rest is on your own time. We could also pay for public transit expenses to encourage public transit use, if available.
