    Thanks for the concise informative article.

    In your paragraph about vehicle maintenance you state that changing “cabin” air filter will improve performance and efficiency. Perhaps you meant “engine” air filter.

    Reducing emissions is an up hill battle with a growing population and increasing mobility. I would like to see some of the long distance trucking replaced by improved rail infrastructure.
