Anyone hear about how electricity will be taxed for use in electric
cars? Seems only fair that they be taxed on and equivalent CO2 or
energy basis at the same rate as gasoline and Diesel. Plug in and the
meter starts calculating your "auto only" rate based on your state,
electric generation being used, ie % Coal,nuke, hydro, wind, solar +
electrical system distribution losses....


Road tax by the mile. A functioning odometer is required by law on all
road vehicles. Mileage is reported at plate renewal.
VERY simple to add road tax to the licence fee.

Snicker! My brother bought a Mitsubishi with the 7 year or 100,000
Mile warranty - and he hit made sure to hit the 7 year point long
before the odometer rolled over 100,000. Of course, the speedometer
cable was disconnected for about a third of the time, and it wasn't
all time it was on a tow-bar behind his motorhome...

Stick and a tachometer, and a simple EFI computer that doesn't freak
when it doesn't see the speed sensor, and you don't need a speedo.

If you really want to cheat, you buy another idnetical instrument
cluster at the junkyard and swap between the two. Suddenly you aren't
racking up nearly as much mileage.

If they try anything like that, it will quickly be hacked.

On most newer cars the odometer is just a display the mileage is
recorded in the ECM. On an Auto trans car I doubt if you could even
drive it with the sensor unplugged, the trans would never shift.

Thank You,

The odomoter is in the engine computer, the instrument panel is just a
computer display of sorts, these days.

Yes, certainly, but it may be getting harder to do that.

Computer technology in the area of encryption could keep any funny business from
happening. Encrypt the speed sensor data stream to the PCM using a symmetric key unique
to the vehicle and your car is locked down. That would require the PCM to refuse to
operate the vehicle if no velocity data is being transmitted. Might suck if your speed
sender fails while you are driving mom to the emergency room but collecting taxes is the
highest moral goal in society. Sorry about mom.
