Automotive Efficiency
Here we have a mental block of thinking of shot term and being individual, neither is working toward the full picture or the future. Exhaust emission controlling, Most people go with what the industry has been doing and that is adding all these mechanical additions to the engine and other areas. This actually cause's more exhaust to be produced by increasing vehicle wait and reducing the engines ability to breath, both accounts reduce effective horse power and thus needing more work to do less. To effectively reduce emissions is increase fuel efficiency and horse power to weight ratio, less power for more work. Another area of contention is time sitting at idle and total travel time. This can be helped by reducing the total number of vehicles on the road. Encourage public transit use, expand public transit access, remove long distance trucking, increase number of train stopping points.
