I won't either. I don't hate them. And i have no need to scream it in caps or bold. But my reasons for opposing them are as soL:

• i don't need yet another company tracking my every movement
• the cars may be safer compared to human drivers, but when they become common, hacking them will become common. Cars with OnStar (which is a small percentage of vehicles) can already be hacked and remotely be brought to a stop.
• their safety is going to come from being too slow, and too cautious. even when all cars on the road are driverless and automated, they'll still ahve to deal with human or wild-life obstacles that will keep their speeds down.
  
• GPS maps, as places grow and change, are a requirment for these things to work worth a damn. say goodbye to traveling down little dirt roads, or offbeat places Google or Bing or whoever didn't maps. Goodbye to navigating complex pieces of private property they weren't allowed to map.
• they have SOOO many problems, that i think most people completely misunderstand just how far we are from their reality. They can't see streetlights when the streetlight and the sun faces the car from the same direction at the same time, they can't handle complex parking decks, they can't handle heavy rain and snow.
• and lastly - they're going to be ungodly expensive. People say "the price will come down". Sure. In 30 years. Look at hybrids and electric vehicles. They've been around for over a decade now, and they price point is still out of range for most americans. To assume 30k is a "good price" is showing just how privileged you are, or showing off the fact that you're a college kid and never had to pay for a thing of consequence in your whole life.
