On Sunday's edition of physicist and superhero Neil deGrasse Tyson's radio show "Star Talk," Tyson interviewed Elon Musk, CEO of Tesla Motors about the possibility of the iconic futuristic mode of transport: flying cars. Musk revealed that he had come to the conclusion that they could never plausibly happen.
"If there are flying cars, then, well, obviously you have this added dimension where a car could potentially fall on your head and would be susceptible to weather," he said, adding that the risk of an autopiloted car crashing would be extremely high.
"We have flying cars today," Tyson added. "They're called helicopters, and they're really noisy. If you want something as heavy as a car to levitate, it's going to be making some noise."
But ultimately, Musk argued, the problem was dimensional:
"Essentially with a flying car, you're talking about going 3-D. There's a fundamental flaw with cities where you've got dense office buildings and apartment buildings and duplexes, and operating on three dimensions, but then you go to the street and suddenly, you're two-dimensional."
