Why do you think emissions from road vehicles continue to increase?

Answer 1

Todays vechicles are a 1000% more efficent than in 1973 when we traded fuel economy and power for lower emissions. With direct ignition systems emissions are now at near 0 percent Hot & Cold . So if your question is why do todays cars and trucks put out more emissions than when they were built, the answer is poor driving habits, poor maintence, low grades of gas and modifying engines or swapping in less efficent engines in place of more expensive quality built engines . Todays cars and trucks foreign or domestic have the highest standards for fuel,emissions and fuel economy with more power than ever before. We have tried Rotory, turbines, diesel ,and now Hybrid,s of all types, the internal engine has just about reached it,s full potenial and limits, but it is still the greatest design ever developed, and so far nothing has replaced it as cheaply as it can be built today or operate under all the same extreme conditions it does without expensive charging stations, special types of fuel, narrow or limited operating ranges and distances or special places to maintain and repair them. And what about recycling emissions? now that will increase because of all the composites we are forced to use to gain all these new emission, safety and mileage standards, that was pulled out of the air and now forced on us to change for our better? Yes some emissions will increase if we don,t use some common sense of what can or should be done to improve our world without setting impossible goals and killing our automotive industry that has made us the greatest free nation and mobile society in the world.
