back to the future II's accuracy

back to the future being my Favorite Movie of All Time and all, i’ve thought about this stuff many-a-time.  i remember seeing BTTF2 when i was 8 and thinking: “how old will i be in 2015?” (answer: 34) and, “i can’t wait for then, that’s gonna be amazing,” and “i wonder if we’ll actually have flying cars."  outlook not so good on the flying cars thing, but pretty sweet to see what else it got pretty right.
