With assistance, for now.

With the door firmly shut, Eliza gets in the other side and says, "An important safety measure in transit widgets: the seatbelt." When she's sure she has Blai's attention she demonstrates pulling it from its housing by the door, extending it long enough, and then clicking the tongue into the holder. "I can help you with yours if you need me to. The idea is that transit widgets go at such appalling speeds that if they hit something, everyone inside gets thrown around pretty badly; the seatbelt ensures that you have a much less rattly and injurious time of it if that happens. In the course of normal operation they do not hit anything but we like to be prepared for things to go wrong."

"Understandable." He puts his seatbelt on just like the demonstration.

Eliza says something to Rupert, and the transit widget rolls forth.

...ah. This transit widget has a property Blai does not like.

"Some people find travel by transit widget mildly nauseating, but I've never experienced this effect myself so I can't tell you much about it," she mentions.

"Is it dangerous?"

"No, just uncomfortable."

Then he will endure it stoically.

"I can look up if there are any known ways to alleviate it."

"It's not very important."

"An expensive intervention to become more comfortable is often not worth it; a cheap intervention often is; I like to find out which ones are which just in case."

"Understood."
