Just hook up a solar powered spark plug and capacitor. When the cow farts poof! It is gone in a beautiful blue flame.

Just remember it wasn't long ago that San Francisco passed a law that banned microbeads. I seem to recall it was a few kilos of microbeads that were supposed to reach the bay each day. MEANWHILE, tons of microfibers have been washing into her bay daily from everyone's Patagonia jackets and yoga pants.

While I don't live in San Francisco, I do spend an incredible amount of time there. Very rarely am I stuck behind a double parked Uber or Lyft driver. When I am, it is only for a relatively short time as they load or unload. Much more frequently I am stuck behind a double parked UPS or FedEx truck and they are gone for extended periods of time as they make their deliveries. They don't seem to be complaining about UPS double parking as UPS drops off their or their neighbors packages from Amazon.
