Rick Schumann's Journal: Here's a scenario for you 'self driving car' advocates to consider:

It's the future; say, 20 years from now. 'Self-driving cars' have become fairly common. Naturally, they're wireless capable for software updates, traffic information -- and other things, like emergency control by 'proper authorities', of course. Now, here's where the dream turns into a nightmare: The 'authorities' (read as: the government) can completely control your self-driving car, totally overriding any destination you've set it for, and even to the extent of the doorlocks and the ability to even open the doors and exit the vehicle. Surprise! You're completely and totally controlled, contained, and have ZERO freedom now. If the government (or hackers, for that matter) want to dictate to you where you're going, when you're going there, and whether you're allowed to even get out of the vehicle, you have no control over it anymore. So much for your civil and human rights; you no longer have any control over your life, or the lives of your family, if you use such a vehicle. Now, let's turn up the Nightmare mode to maximum: In this ultimate dystopian future, you're not even allowed to own a vehicle that isn't self-driving, regardless of whether or not it's got manual controls for a human operator. You want to go somewhere? You're at the whim of police, the government, hackers, and whoever else has their hands on the real controls. Modifying your vehicle so it's immune to wireless control is a felony with long jail time and a huge fine "because that's unsafe". Public transportation is also self-driving and subject to the same rules; unless you walk or are on a bicycle you're at their whim, and walking or riding a bike gets you stopped and questioned by the local LEOs as suspicious.

Sound too extreme? It's supposed to, that's how cautionary tales are written. Think I'm a nutcase? Nope, I'm just trying to illustrate a point: Be careful what you wish for. If you're not controlling the tools you use, then maybe the tools are controlling you.
