In view that motor sports (motor racing, rally cross, motorbike racing, truck racing etc) are a waste of precious remaining hydrocarbon fuel reserves, should there be a worldwide ban on these sports?
As regards other sports & other activities that either directly or indirectly use fuel to enable spectators to reach the ground or for people to fly say from Paris to Miami, there is a PURPOSE for these.
Motor sports, on the other hand, race around a track, use up a lot of hydrocarbons simply to produce a winner.
