It's 2019, the year Blade Runner takes place: I can has flying cars?

Welcome to 2019, the year in which Ridley Scott's 1982 sci-fi film masterpiece Blade Runner is set. And as predicted in this loose adaptation of a 1968 Philip K. Dick story, we have flying cars.

The reason you don't have a flying car was explained by author William Gibson, who famously observed, more or less, "The future is already here – it's just not evenly distributed."

If you're Sebastian Thrun, you've already flown in Kitty Hawk's Flyer, which is more flying boat than flying car. If you're not, chances are you will have to wait a bit longer to live your sci-fi noir transport fantasy.

Topics include flying cars, artificial pets, voice driven photo enhancement, the Voight-Kampff machine, ad-festooned airships, space colonies, artificial organs and replicants.

    Yeah, I much prefer the Blackfly octo-rotor "biplane", for both engine-out safety and aesthetics. Though the bit about staring up at the sky when hovering would take some getting used to. Grandma's not going to be carrying a pot of stew on her lap in that sucker.

    I would think though that engine-out scenarios would also be a LOT less likely in an electric aircraft - a motor generally has only have one primary moving part instead of dozens, and no liquids, lubricants, pressure seals, etc. An engine-out scenario is pretty much limited to a broken power cable or frozen bearing, both of which should be easily caught in routine maintenance. Even a damaged cooling system will only limit the output rather than eliminating it, and an efficient electric motor only needs to shed a few percent of the shaft power as heat, rather than more than 100%, as is normal for ICEs (even rocket engines are only about 60% efficient and they're leading the pack, most are firmly below 50%) And if the risk of an event occurring in the first place is substantially lower, you can get away with much less robust risk mitigation while still achieving the same overall risk profile.

    Of course electricity does nothing for propellor-out scenarios - but how common are those, exactly? And how many rotary-wing aircraft can handle even one wing being severely damaged? After all, a responsible risk mitigation strategy has to be based on the understanding that perfect safety is unachievable, and then start mitigating the risks with the highest risk to mitigation cost ratio until either adequate safety is achieved, or the expense becomes so great that the product isn't viable.
