LOS ANGELES (AP) — Electric cars may be good for air quality but they're still a costly novelty.

Now a coalition of community and environmental groups wants the vehicles to go mainstream.

The coalition — which calls itself "Charge Ahead California" — launched a campaign on Thursday to put 1 million more electric cars, trucks and buses on California roads.

The state, led by Gov. Jerry Brown, already has been promoting electric vehicles for environmental reasons.

But the coalition says more money should be invested in programs to bring electric vehicles to low-income areas.
