Now, which one of them is capable of driving in the States? Though LA to LV isn't exactly the longest road trip, but that's still about 5x more competent than we'd expect from most Vtubers. (Though that drive is legitimately quite dull unless you've got a sports/super car, as a note.)
Driving for a whole road trip in a country with the opposite traffic direction from your own is legitimately impressive. Just being a pedestrian in a left-hand traffic country was stressful for me, can't imagine what operating a huge RV at motorway speeds when all my driving instincts are inverted must be like.
As amusing as the thought of either Korone or Botan driving an RV on US highways would be, I'm pretty sure the real answer is American Staff-san was driving.If you're used to driving, it's not that hard of a change and you can get over it pretty fast. However, Tokyoite Japanese able to drive is the surprising part in the first measure, though thinking about some of Korone's time off helping her mother I'd guess her?
Though the thought of unleashing Korone on the roads of America is actually slightly terrifying. At least its not Miko.
