I've driven for 31 years now, and a paper map has never failed me. It does not require electricity, nor have all the maps I've purchased over the years put together cost me anything lile $2000. All the old ones still work, unlike the standard electronics -- years and they are junk.
More to the point, an $4000 EZL module every three years ain't gonna cut it in a car. Ditto for the $8000 engine control module, the $4000 computerized climate control (whatever happened to dumb servos -- all it does is act as an automatic thermostat!??).
If air pollution is a problem, the answer is to not use personal automobiles, and to live very near where you work, not endless, very environmentally damaging, electronics.
