It's a very good question. I'd like maybe to respond with an alternative approach.
Maybe one way to do it is to start with heavy-duty mobility buses and trucks. You start with a fleet-operated vehicle. Those vehicles have the largest contribution to emissions compared with a personal car, which is used only a couple of hours per day. We should start with a fleet of buses or trucks. We talked earlier about warehouses and distribution centres. It's much easier to imagine that you have one refuelling station at a fleet location, and then the same infrastructure can be used for tens or hundreds of vehicles.
I think that would be the way to start. You start where you have the biggest impact on emissions. You start with a fleet-based vehicle, and from there you can grow. Maybe it's easier to do it this way than starting with the passenger car market.
