Anyone with a broken down car may have too, lol. I even already presented this possible scenario in my original comment. If what you’re suggesting was true, people wouldn’t be able to enter with cellphones, wheelchairs, or any other battery powered device. Ignorance of the drivers is too large, but if you explain why, most will let you, since you know, it’s not illegal…. You do know the bus has a few already in it….? Yeah…? Or even someone bringing home a case of drinks, same weight and possible consequences, and totally legal. You’re focusing too much on the irrelevant shit lol.

Here’s even a picture of one and someone doing so.
You’re just a fool I guess, dunno what anime has to do with the original topic.
