E85 is 85% ethanol, 15% gasoline, not the other way around. A 10% ethanol blend (10% ethanol, 90% gasoline) is called E10, not E90. Using E10 reduces your fuel economy by about 3–4%, and a 15% blend reduces your miles per tank by about 4–5%, assuming a modern, fuel-injected engine. I would expect the impact to be worse for an engine with a carburetor, but I don't know for certain. Either way, I'm pretty sure it's nowhere near 20% even with older engines.

Yes, if it were legal to sell E90, it would reduce your fuel economy by somewhere in the neighborhood of 20%. Of course, your car wouldn't start in the winter, and in most cars, parts of your fuel system would likely rust out pretty quickly, spewing fuel all over the hot engine, thus ending your life in a blaze of glory, so fuel economy would be the least of your problems....

I'm a little bummed about this. My first reaction was, "Oh, cool. This is just like the idea I had a few days ago." Then, I realized they're trying to do it from a single photo instead of taking advantage of the camera hardware to obtain actual depth info.

You have a lens that can focus. Take your shot, throw the focus off as far as you can (in whichever direction you can move the focus farther, by some definition of farther), then take a second shot. You can then compute some reasonable approximation of distance for every pixel without guessing. You can also likely compute a reasonable bokeh based on the size and location of bright areas in the out-of-focus areas and based on how much they spread in the out-of-focus shot. It's not perfect, but I suspect you could get close enough to fool just about anybody.

His antipathy towards our most important civil right, the right to self defense, shows that Stevens was never fit to be admitted to the bar at all. The second amendment doesn't need fixing, it needs ENFORCEMENT.

The right to keep and bear arms isn't for the government to grant or withhold, and the second amendment doesn't even presume to do so. It acknowledges the right as pre-existing, it cites one important reason for preserving it, and forbids the government from infringing it.

The sick fuck principal and the sick fuck vice-principal at my middle school just loved to paddle kids until their asses were purple.

Never encountered that in school, but by 9th grade I already knew what kind of damage you could do to someone if you knew their name, address and SSN.
