Musk told Bloomberg's Max Chafkin he thinks flying cars are a dumb idea for city travel in a profile about his tunnel plans published on Thursday. He said even though his plan to build an underground network of tunnels might seem crazy, it's actually less crazy than flying cars.
“Obviously, I like flying things,” Musk told Bloomberg. “But it’s difficult to imagine the flying car becoming a scalable solution.”
Several companies are pursuing flying cars. Google co-founder Larry Page is funding secretive startup Zee.Aero to build a flying car. Uber has also launched a flying car project.
These ventures don't involve building a flying car per se because they aren't intended to drive on roads. Zee.Aero is building a Vertical Take-Off and Landing (VTOL) aircraft that, like the name suggests, can take off vertically without a runway. Uber plans to use VTOL aircrafts for city transit, but plans to partner with other companies and the government to actually build the aircraft.
Musk said flying cars need to generate a lot of downward force to not fall out of the sky, which would result in a lot of wind and noise for people on the ground. He also said there's a risk of falling debris if falling cars were to get in a mid-air fender bender.
“If somebody doesn’t maintain their flying car, it could drop a hubcap and guillotine you,” Musk said. “Your anxiety level will not decrease as a result of things that weigh a lot buzzing around your head.”
