they are going to say, we're replacing a taxidriver, a taxidriver costs x cents per kilometre, so we take 10% off and we can make a hell of a lot of money because we need to earn back the $100 billion we invested, so until we get that cost down, really, to what it actually costs to operate, plus a small margin, then i think we will start to see this autonomous mobility on demand really being a lot cheaper than owning a car, and a big switch. and that should enable our mission again, if we make sure those cars are electric or running on solar. thank you, arjo. now, linda, of course, electrical vehicles in general help with emissions and help even more when they're powered with electricity from renewable resources. all this is great, but the batteries are a problem, aren't they? they contain a lot of rare earth metals that need to be mined at scale. for example, lithium is a key component and you can get that out of mines say, for example, in chile's atacama desert. is there a plan in place
