It's coming.
When the motor vehicle got invented, most people swore that they would never ride in such a contraption. They'd stick to their trusty horse and buggy - thank you very much.
Then when the airplane came along, most people swore that you would never catch them in such a contraption. "If God intended us to fly, why he'd have given us wings" they used to say.
So it's coming and eventually people will come to accept them. Personally I can't wait for them to come to New York City as I hate dealing with taxi drivers and riding the subway has a lot of downside.
The responses to this thread are very interesting. Who knew so many Freepers were Luddites.
