New fuel standards being proposed will be met with much smaller cars (as it usually is) so there will be a reduction in car pooling, and a reduction in cars confortable enough to ride in for any length of time, forcing people onto mass transit, which is the plan in many areas anyway.

Government rarely takes a cut, it just increases it's cut.
