And so I guess the issue which may become apparent here is that if those maximum fees were the same, then there's effectively a disincentive once the new vehicle exceeds a particular point; actually, you're effectively creating an opportunity to bring in more higher emitting vehicles without actually that continually—costs just continuing to go up. So the question there is: is it just a raw "This will be how much you will pay if it exceeds the target for every single gram?" And will there be a maximum fee? And if so, will those maximum fees differ between a used vehicle and a newly imported vehicle?
