I climbed into the front seat of the air taxi, buckled the seat belt and braced as the aircraft lifted off. The futuristic cityscape of Busan, South Korea, dropped away, and a digital avatar popped up on the windscreen with a message.
I couldn't answer as a wave of motion sickness hit me. The virtual reality goggles combined with motion-simulating seats pitching back and forth and side to side made it feel like I was actually hovering and maneuvering in the air. They also made me so nauseous I had to close my eyes for the rest of the three-minute journey.
