As with all discussions of technology that is so new it doesn’t really exist yet, some people compare it to successful inovations (e.g. the Internet) in order to preridicule the pessimists, and some compare it to market failures (e.g. video conferences) in order to make the optimists sound suspect. There is a middle outcome too, that of robotic vacuum cleaners that are slowly gaining market share and that of the paperless office that came somewhat true but didn’t defeat the office stuffed with paper.
The image above exemplifies just a few issues that driverless cars need to be able to handle. It is going to turn right in the crossing and the sun is reflected in the side-window of the green car. An experienced human driver would realize that it is impossible to know whether the car behind the green car blinks left or not, due to the reflection of the sun, so he/she will wait a little. Can a robot ever be sure that a flashing indicator is unlit?
