Ridicilous. As if they're little kids. Anyway, shouldn't be a problem. I wondered why they drive by themselves anyway (if it's not in their private time, but for work) I mean it must be 100times more relaxing to be driven around Tokyos traffic than having to drive yourself. But they are male, they probably need the adrenaline....I would love to have a driver, sadly I have to do it myself and get almost heart attacks every 500 metres.
