The House of Representatives passed a bill to require driverless cars
to have some vague sort of better security against crackers, on the
reasoning that terrorists might crack them.
There's nothing wrong with that goal, but it completely
ignores the much more important danger: that state agents, with the
collaboration of the car manufacturer, could make the car take you to
the black site of the secret police.
If driverless cars become common, they will be used in all countries,
including China, Cambodia, Egypt, Turkey, and Salafi Arabia, to
mention just a few in which tyrannical practices have recently been
reported on here. Even if you suppose this can't happen in the US,
that should matter. But if you don't think that could happen in the
US, read about what the Chicago thugs did for years.
