So we buy vehicles for a lot of different missions – one is to go shopping and in fact it's a big mission. Now today if you can start as we already see people push the button in delivery of, you know, shirts and ties and all the things you can buy on Amazon Electronics. Tomorrow will look nothing like today and these types of pushing the button and delivery systems will change your reason even to go shopping. It won't go away but when you go shopping you're just not going to go for 10 minutes to stand in line for 20 minutes. You'll push the button, it will be delivered, but when you do go you're going to spend a long time. You'll need a big vehicle to take care of that. So the mission is different, the number of miles traveled is different and the infrastructure around that will be different. It'll be a nice opportunity for the auto manufacturers and other service providers.
