Surprisingly so! Humans really don't like being confined, and travel is stressful enough as it is... One of the options for my senior design project (~5 years ago) was designing an artificial skylight for a hyperloop-style vehicle. Evacuated tubes make natural lighting difficult, and they'd already determined this was going to be a major hurdle for making the thing an attractive option for passenger transit. They wanted it to respond to the vehicles movements as well. Cool project!
