In addition, the engine size distribution is moving in the wrong direction for energy and emissions savings. Finally it is likely that the infrastructure that has been needed to accommodate such an increase in vehicle numbers has been a drain on national resources that is now locking in development to
In addition, the engine size distribution is moving in the wrong direction for energy and emissions savings. Finally it is likely that the infrastructure that has been needed to accommodate such an increase in vehicle numbers has been a drain on national resources that is now locking in development to this transport mode. This path  makes mitigation in this area difficult and more or less constrained to fuel switching (either biofuels or electricity) rather than mode changing for instance to improved public transport systems.
