that story is hugely over-blown. the "hack" cited was for an
after-market pc-based system, and it's as vulnerable as any p.c. most
of the systems on cars are what's called "embedded". typically they're
not networked or accessible, so there is no entry means, and they're
usually "locked" at the chip level - primarily to stop competitors
peering into their code.

now, there are parts of the system that are accessible like gps, but
i.m.o, anyone willing to pay $3000 for a gps option that's inferior to
many after-market $300 systems, that you have to pay through the ass to
get upgraded, or worse, requires a monthly subscription to operate, has
to be out of their mind. especially when those kind of systems are
capable of calling in when you're speeding, etc. if anyone wants to
hack those things, go ahead and be my guest.

there is a trend towards "upgradable" ecu software, but that's by means
of an entire encrypted o/s "image", it's not readily accessible in the
way that a p.c. is. you can monkey with it by replacing the image with
one you've tried to unencrypt and modify, but that still takes physical
access. and frankly, once somebody has physical access, they can
replace the ecu with their own and drive away anyway.
