David Hasselhoff was onto something

We all know that hybrid cars are more fuel-efficient than regular cars, right? Not always: turns out "intelligent" cars that drive themselves -- some of which are already on the road -- are more fuel efficient than even hybrids. By using using sensors and receivers to predict traffic conditions and then adjust speed accordingly to prevent "stop-start" driving that decreases efficiency and causes more traffic, the "intelligent" cars (or auto-autos, as we like to call them) boast about a 33% efficiency improvement over regular cars (versus just 15-25% for hybrids). So imagine the fuel savings if these intelli-cars were also hybrids! Also, as Hank from Ecogeek points out, the intelli-car tests were conducted on roads filled with "regular cars," and one can only assume that their efficiency would be collectively greater still if all the cars on the road were intelligent. What it would be like to drive -- or, more accurately, ride -- on such a robot-controlled highway remains to be seen, but this blogger bets that road rage levels would decrease along with emissions.

Don't Have Space For a Christmas Tree? Decorate a Pineapple Instead

Christmas trees aren't for everyone. Some people can't fit a fir inside their cramped abodes, while others are turned off by the expense, or by the idea of bugs hitchhiking their way inside. Fake trees are always an option, but a new trend sweeping Instagram—pineapples as mini-Christmas "trees"—might convince you to forego the forest vibe for a more tropical aesthetic.

As Thrillist reports, the pineapple-as-Christmas-tree idea appears to have originated on Pinterest before it, uh, ripened into a social media sensation. Transforming a pineapple into a Halloween “pumpkin” requires carving and tea lights, but to make the fruit festive for Christmas all one needs are lights, ornaments, swaths of garland, and any other tiny tchotchkes that remind you of the holidays. The final result is a tabletop decoration that's equal parts Blue Hawaii and Miracle on 34th Street.

In need of some decorating inspiration? Check out a variety of “Christmas tree” pineapples below.
