Will be $0.28/gal state plus $0.184/gal Federal.
Total $0.464/gal.
$150 ~ 323.28 gallons
$50 ~ 107.76 gallons
30mpg x 323.28gal = 9698.28miles
Now let's do some hybrid difference math:
(1/35mpg - 1/50mpg) = 1/75 gpm
$50/$0.464/gal/(1/35mpg - 1/50mpg) = 12571.84 miles
$50/$0.464/gal/(1/30mpg - 1/45mpg) = 9698.28miles
It's a continuation of the now-usual dumbness. If one group pays based on (fuel economy, miles traveled) and another pays based on a fixed fee or fixed supplement, something's broken.
Nobody has bothered to ask the simple question: Given that fuel consumption does not directly correlate to the impact of a vehicle on road construction and maintenance costs, for what is it acting as a proxy? Answer that question and it tells you how to match the system for other vehicles.
The politicians fail to recognize or simply don't care about the actual effects of plug-ins and hybrids on fuel consumption and the trends in electrification:
- PHEVs in particular have a disproportionate impact on fuel consumption in heavier traffic.
- PEVs ranges are increasing
- BEVs are going from short range to long-range
- Per mile driving costs are lower
- The price of electrification is decreasing
The effects and trends point to more electric miles per PEV, self-selection of higher-mileage drivers and the possibility of a catastrophic (in the mathematical sense) increase in electrified miles. They haven't fixed the pricing problem. Surprise, surprise.
What's really needed is a ground-up review of the source of road costs, from which they can calculate an ideal pricing formula, from which they can _then_ come up with a simplified system that won't cause hand-wringing and self-made funding crises.
