It's something we are considering, to be sure. We aren't expecting the vehicles to be completely self-driving. Already, in the industry, a driver can release the wheel for an hour at a time. The vehicle can stop and accelerate without driver intervention, given the number of sensors and cameras all the way around the truck. That really makes the driver's job easier. I play that up as an advantage in my efforts to recruit drivers, especially young people. The amount of technology trucks are equipped with today is incredible. All of those sensors and cameras make the trucks safer, by the way, which is also encouraging.
Advancements are happening quickly right now. Everything is changing, but we see that as very positive for the industry, not just because it improves safety, but also because it helps us recruit people.
