  • I was actually impressed when I took a bus across state lines in the U.S. recently.

    Someone was complaining about the charger on their seat not working.

    Turns out that the driver has full control of the power to the USB ports on the bus and can turn them off and on at will… and they apparently they turn them off BY DEFAULT.

    If someone WERE to figure out a way to get from the USB port in the seats to the CAN Bus on the vehicle itself, having a hard-wired physical switch that cuts power/signal to the ports is potentially a fairly effective security measure as long as there’s not a memory buffer you can compromise and run stuff from.
