Multi-track drifting. Also while some infinities are smaller if you're just counting out an infinite number of individual humans then I'm pretty sure they're the same size infinities one is just social distancing. Smaller infinities are ones like those in between each part of the bigger infinities. To represent a smaller infinity you'd maybe have to have an infinite number of smaller humans crammed into a spot the size of one of the spaces between the humans on the other track, or something along those lines. The real number track does contain smaller infinities between each integer via infinite decimal points but I don't think one track would technically be smaller than the other in this case since they run parallel to each other but neither are technically limited in the "length" of their infinity so to speak. But I could be misremembering how they classify smaller infinities.
