One caveat here is that it’s not clear if it’s “4 deaths downstream of the procurement of a OneWheel” or “4 deaths attributable to this particular failure mode”. There might be some number of “died riding a OneWheel after getting hit by a car” deaths, but arguably that particular type of fatality should be chalked up as “downstream of the procurement of a car”.
