Re: Language/Accent?
"And what if the questions are being asked in a language in which the perfectly legitimate traveller is not fluent, and is struggling to understand the question & formulate an acceptable answer from their limited vocabulary? "
The article says the questions will be presented in the travellers' language. Not sure they will be able to accommodate all travellers in the case of some exotic languages... but then again if the system doesn't handle a language, what's teh chances that any of the border guards can communicate with that person anyway?
