Your numbers and/or units are wrong.

That is only 33.48 megabytes.

But your error is before that.

3600 * 24 * 31 = 2678400 sec/month (that one you got right)
2678400 sec/month * 100,000,000 bits/sec = 267,840,000,000,000 bits/month (you had an error here)
267,840,000,000,000 bits/month / 8 bits/byte = 33,480,000,000,000 bytes/month
33,480,000,000,000 bytes/month / 1,000,000,000 bytes/gigabyte = 33,480 gigabytes/month
33,480 gigabytes/month * 15 $/gigabyte = $502,200

Normally there are two _separate_ CAN busses, one which handles all the critical crap, and one which handles the infotainment and comfort stuff. There's a module which connects the two, providing read-only queries from the second to the first. None of the hacks breached this system.

Oh really? Then how did that Jeep Cherokee hack via the infotainment system work?

from http://www.wired.com/2015/07/h... (emphasis mine)

As the two hackers remotely toyed with the air-conditioning, radio, and windshield wipers, I mentally congratulated myself on my courage under pressure. That's when they cut the transmission.

Immediately my accelerator stopped working. As I frantically pressed the pedal and watched the RPMs climb, the Jeep lost half its speed, then slowed to a crawl. This occurred just as I reached a long overpass, with no shoulder to offer an escape. The experiment had ceased to be fun.

Is it any different then say apt-get using unsecured http or ftp connections?

In addition to the package .deb files being signed, the official package repositories have signed package indexes. I suppose one could just serve up a modified index without a signature, but apt might warn or error on that. (I haven't checked this part)

From the cable tear-down, it does not appear that either end had any of the shielding connected to the plug shield.

With XLR cable connections, you have your shield, which IS connected at both ends, and your signal ground, which is isolated from the shield.
