Driverless cars, high speed rail, and climate comedy

1. I'm more inclined than not to support high speed rail in California and elsewhere - we need to get people out of the sky.  OTOH, I've wondered for several years whether the otherwise-beneficial role of driverless cars could turn HSR into a financial dinosaur.  Those driverless cars could hook up together as a pod, and even if they can't go 200 mph, they could go faster than humans could drive them and be an acceptable way to travel from San Francisco to Los Angeles when you can make productive use of the entire time.

Maybe building HSR in stages makes sense so we can cut our losses if needed.

2. Marginally related subject:  American University and Sierra Club are running an Eco-Comedy Video Competition for the funniest, under-three minute original video educating people about climate change.  I plan to submit 179 seconds of Joe Bastardi talking, but maybe you can think of something even funnier.
