Looking at the history of jetskis/wetbikes etc., the assumption that poor operation
will only injure/kill the operator, thus 'improving the gene pool', is ill-founded. Many
uninvolved innocents have been severely injured, and killed, by idiots on those sorts
of water vehicles. The flying equivalent would have much greater opportunity to injure,
maim and kill bystanders. If such a thing becomes a reality, it will be severely restricted
as to where it can be operated.
Frankly, it's always been a solution looking for a problem.
