In California, all cars must periodically submit to a “smog check” to verify that the catalytic converter works and that emissions are within a certain range.
Today I bring my car in for the check. When I pick it up, I ask “Is the car ok? Does it pollute?” “Of course it pollutes,” says the car technician guy who just charged me \$142.99 for ten minutes of work, “This [the car] is the worst invention ever made. It’s destroying our planet.”
