How to address the problem? The report says travelers susceptible to the problem might try closing their eyes or even sleeping. And, if necessary, they might try commonly available medications. Some travelers also have had success with bands that tap into pressure points on the wrist.
The good news, the report indicates, is that autonomous vehicles could be programmed to deliver a smoother ride than a conventional vehicle, a step that's also likely to reduce motion sickness.
