Will higher speed limits be a net benefit to NZ (when considering alleged economic gains, probable increase in planet warming emissions and probable increase in severity of road accidents).

Am I missing something? .. or perhaps Simeon Brown (Minister of Transport) is an unabashed "petrol head" who wants higher speed limits at any cost?

A vehicle traveling at a steady 110 kph would save only 5.5 minutes over another that is traveling at a steady 100 kph. Is it a worthwhile saving? Is there anywhere in NZ that it is safe to travel at a steady 100 or 110 kph for 100 km?

Would a truck and trailer unit still tailgate at 110? (even though the heavy vehicle speed limit is currently 90 kph).

Would the savings of a few minutes, here and there, compensate for the increased severity of road accidents (with associated economic costs) and NZs increased liability for greenhouse emissions?
