While I get that the autonomous system wasn't at fault, the real question is, "Were the accidents something a human driver could have avoided?" I'm a professional delivery driver and one of the things that's constantly drilled into us is to essentially watch out for the stupid people. Sometimes you have to yield right-of-way because it's clear the other driver isn't going to. Do autonomous cars know that?

Rule of three: Original copy, on site backup, off site backup. Otherwise you're not truly protected. I'd say SD cards, in a Pelican SD card case, in the safe for the local backup. Then look into an encrypted off site backup. The key is to make sure it is encrypted *before* it leaves your computer, and that the provider does not hold the key. Many providers offer this, even if it's not turned on by default.

Another hand goes up for the amazing C-64! I remember writing a program and convincing my older sister that I'd changed her grades at school. She told the principal and to this day hasn't forgiven me for embarrassing her. I also got SAM, a speech synthesizer that gave a few extra commands in BASIC. Eventually I had a program that picked up the phone, dialed a number, and then spoke whatever you typed onto the phone line. My friend and I carried on a 5 minute conversation with a girl using that program and she never knew who it was (my god, i was a nerd)!
