It would be quite an accomplishment for Sentra to be able to maintain his fuel mileage,
AND
Satisfy his desire to not be a contributor to increased pollution.
It also means that the most dedicated hypermilers may be driving in ways that cause increased emissions. If that is resolvable then you have super high mileage and significantly lower total emissions than any normal driver., both in percentage and total volume. A smaller footprint it total, and certainly deserving of a dedicated effort.
It certainly is a goal worth pursuing and an admirable sense of ecological responsibility.
A tip of the hat to a man who is dedicated to both goals.

I have often wondered why with all the rules that auto manufacturers must follow and all of the devices they must include for safety, pollution etc.
Why the law does not require a simple 5lb $20 device on every car that reduces pollution and increases FE, a block heater.
Honestly I can't understand why every US made combustion engine car does not have one given how effective they are, not to mention like an EV you could "preheat" your car before you drive.
Penny wise, pound foolish.
