Submission + - MRIs show our brains shutting down when we see security prompts... (arstechnica.com)

antdude writes: Ars Technica reported that "Magnetic Resonance Imaging (MRIs) show our brains shutting down when we see security prompts. This is your brain after repeated security warnings. Any questions?

Ever feel your eyes glazing over when you see yet another security warning pop up on your monitor? In a first, scientists have used magnetic resonance imaging to measure a human brain's dramatic drop in attention that results when a computer user is subjected to just two security warnings in a short time..."

You are somewhat the rarity with your vintage car. For most people, drive by wire is already a thing. The throttle has been drive by wire for years on most cars, and some of today's cars are steer by wire. (Yes, there is manual reversion if it fails, but in normal driving you have no mechanical connection between the steering wheel and the wheels of the car). Many cars can brake independently of the driver. Even my 2007 Civic has traction control and ABS fitted as standard.

Traffic would probably flow considerably better in a city full of self driving cars. A lot of the chaos of city driving is because of human error and human reaction delays.

You only have to fly over a traffic jam on a major highway to see problems that could be significantly alleviated by self driving cars that communicate with each other. Quite often you see traffic jams with no explanation - a mile of stationary traffic, but there's no obstacle in front and none behind. What happened is two hours earlier someone slammed on their brakes, someone following too close had to brake harder, and eventually the whole highway stops. As long as traffic is not leaving the stopped area faster than it is arriving, you get a self-sustaining traffic jam long after the original cause has gone away. The self driving car will reduce the instances in the first place of the cause, and if it does happen will be able to as a group moderate their speed in such a way that you don't end up with a mile of stopped cars. Instead of the next car only starting after it has seen the previous one begin to move + reaction delay, all cars will be able to start moving at once or nearly so.
