Self-Driving Car Test

“We announced our self-driving car project in 2010 to make driving safer, more enjoyable, and more efficient. Having safely completed over 200,000 miles of computer-led driving, we wanted to share one of our favorite moments. Here’s Steve, who joined us for a special drive on a carefully programmed route to experience being behind the wheel in a whole new way. We organized this test as a technical experiment, but we think it’s also a promising look at what autonomous technology may one day deliver if rigorous technology and safety standards can be met.” — Google

Optical Illusion: The Tilt

“How this ‘works’: The sets of opposite diagonal lines in this drawing cause us to perceive the top rectangle as leaning toward the right when it really is not. Removing the lines proves that the rectangles are parallel. What also aids in the illusion is the triangle drawn on the right end of the top rectangle (we subconsciously perceive it as weighing down the right side… but only when the diagonal lines are there).” — greeenpro2009
