I think that's a very sensible option that Simeon Brown has put forward, because already we are starting to see vehicle sellers advertising pricing that is confusing for consumers. And why wouldn't they? They're in the business of selling vehicles and they're trying to maximise their competitive advantage against other manufacturers and other brands and other sellers of vehicles. Some of the advertising seems to include the clean car discount already taken into account, and some of it doesn't, but there doesn't seem to be any clear or consistent mechanism for consumers to understand what the ticket price of the vehicle will be. I would've thought that—again, putting aside their academic and sort of ideologically driven views about who should have what cars and when they should be driven and how they should be driven and how they should be powered—it would make sense to make it very easy and clear for consumers, potential purchasers of cars, to know what the actual price is. And right at the minute, I think that there is reasonable concern amongst consumers about a confused pricing mechanism that doesn't mandate or require one way or the other. Should the price on the windscreen in the car yard have a price that reflects the discount taken off it, or is it a gross price or a net price? And what is it that the consumer is actually going to have to pay to pick up and purchase that car?
