We are looking at that million-mile truck all the time and we're almost there. Now all of the equipment manufacturers have moved that out to 700,000. So obviously we are moving in the right direction. We look at the initial cost, the residual value and then the cost of operating it, and keep trying to fine tune all of the components on the various units to arrive at the best cost figure. So the trucks are better today, they are more comfortable and easier to drive.
Roads are better, too.
Yet it is an open question whether drivers have it easier today. The equipment has changed, but so has the job itself. I don't know that it is easier, but many years ago we had only two-lane highways if you went to the West Coast. I think the Interstate System has made driving amazingly easier. We've really worked on the environment the driver works in.
