I'd love to see a similar comparison for a full compendium of cars. Do BTC prices correlate with the number of Nissan Skyline GTR's that get imported? What about 911 GT3's? Would perhaps reveal something more causal than just BTC vs Ferrari's.
Is this hallucination, or is this actually quite human (albeit a specific type of human)? Think of slimy caricatures like a used car salesman, isn't this the exact type of underhandedness you'd expect?
