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.
The real question is…why are the data lines connected to anything in these chargers, let alone connected to the CAN Bus? There’s no need for security if you just don’t have access. Something tells me either the company doesn’t like their customers, or the bus driver was just a dick.

Why not both?
Or it might just automatically turn them off when so fools aren’t draining the battery without the bus running.
this is dumb there is 100% no data connection to those
