Self-driving cars can be fooled by fake signals

Its also easy to put a fake cardboard obstacle on the road. People tend not to do it.

It is no different to shining a laser pointer into drivers eyes from a motorway bridge. The police will show up pretty fast.

As much as I want self driving cars I'm a bit skeptical about this tech. I'm sure many of you are as well. Technology is meant to be manipulated whether for good or bad. And it always seems that the bad outweighs the good.

How can manufacturers assure the masses that their cars won't get hacked or manipulated in a manner that leads to something tragic? I'm thinking they can't.
