I'm environmentally concerned but meh...as has been said, it's everyone's fault, not just 'big business' or whatnot. Maybe if California spent more money on mass transit that fits the local lifestyles and car-dependant spread-out city layouts, people might actually use them. But that would cost too much to rehaul city designs and create fleets/systems, easier to sue.
I can understand the motivation behind this frivilous suit but it's not the way to go about it. They may as well sue every individual who ever bought a car.
