This was 1978, when flying was still an occasion, a special grand event that took planning and care. I worked as a TWA flight attendant then. I stood in my Ralph Lauren uniform at the boarding door and smiled at the passengers through lips coated with lipstick that perfectly matched the stripe on my jacket. Mostly, the passengers smiled back.
The Jetsons had them in the 1960s. They were the defining element of 'Knight Rider' in the 1980s: cars that drive themselves. Self-driving cars appear in countless science fiction movies. By Hollywood standards, they are so normal we don't even notice them. But in real life, they still don't exist. What if you could buy one today?
