I'm going to stop you there. I think we've heard concerns about carding and targeting and that humans will have to implement this. In the ways in which law enforcement may exercise where a roadside RIDE test is levied, so that it's not targeting certain neighbourhoods, could we not come up with operating principles that were almost randomized in advance in terms of where randomized testing would be so that it wouldn't target groups?
Is it not possible to come up with an operational approach to avoid some of the prejudices you're suggesting?
