There's a very simple reason for that: 90% of the time, people are not going to charge at these things. Charging networks are not actually analogous to gas stations, because their utilization, by definition, is that when you go home—you have a garage at your place or a driveway—you're going to plug in your car and you're going to wake up with a full charge. The data we've seen is that 90% to 95% of the time, that's what's going to happen, but if you're going on a road trip or you're taking a longer trip a few times a year, you're going to need public charging.
The idea is that the business case, inherently, is challenging for charging infrastructure. That's why I mentioned that there is going to be high highway usage, for which there's going to be a good business case. There are cases in which there will never be a business case. Maybe that risk can be shared, and a charging operator can have a portfolio in which some make money and some don't, and then it balances out. However, I think that public money is really needed to help grease the wheel so that we can actually have a self-sustaining model.
