+ | [https://techcrunch.com/2016/08/10/are-consumers-automakers-and-insurers-really-ready-for-self-driving-cars/ The programming] of {{w|self-driving cars}} has been in the news lately, as engineers and philosophers debate what rules the cars should follow in dangerous situations (for instance, what to do when forced to choose between hitting a pedestrian or swerving into oncoming traffic). [[Randall]], in the form of [[Ponytail]], suggests one approach for solving this problem: to think of the car as behaving like a horse, using its own intelligence and ignoring dangerous commands in the interests of self-preservation. | ||
− | The comic begins with Ponytail claiming that in the old days, riding a horse or driving a horse drawn vehicle while drunk was less dangerous than {{w|drunk driving}} today. Given the higher speed and the denser traffic today this might seem plausible. On the other hand, modern cars have seat belts, airbags, and other features designed to save lives when crashes do occur; horses and horse-drawn vehicles lacked these safety features. | + | The comic begins with Ponytail claiming that in the old days, riding a horse or driving a horse drawn vehicle while drunk was less dangerous than {{w|drunk driving}} today. Given the higher speed and the denser traffic today this might seem plausible. On the other hand, modern cars have seat belts, airbags, and other features designed to save lives when crashes do occur; horses and horse-drawn vehicles lacked these safety features. Ponytail expands the argument by stating the horse itself will (likely) not also be drunk and acting in the interest of its own self-preservation. |
− | + | This segues into a scene with White Hat, bragging to Cueball and Megan about the features of a car (either to sell the car or simply boast; it's unclear whether White Hat is acting as a salesman) by comparing the features to those of horses. Car engines are traditionally measured in {{w|horsepower}}, which (roughly) compares the power output of the engine to that of a horse. White Hat goes a step further, claiming he can measure the car's onboard computer as a number of "horses", comparing the car's ability to mitigate for a drunk driver and/or avoid obstacles to that of a horse. | |
− | + | The title text features more comparisons of the car to horses. Apparently the car has 240% of a horse's decision-making ability while producing only 30% as much poop. So even with 3.5 horse-intelligence it may only have 2.4 times the decision-making ability (assuming it's the same car). A cars "poop" would be it's exhaust, which is usually not found on the road in the form of solid waste but could still nonetheless be measured, as it contains mass. While no source is stated for the 30% ratio, the point that cars are less polluting that horses is surprisingly valid. Before the invention of the automobile, city streets were commonly filled with horse manure. | |

Note that riding a horse while drunk is in fact still dangerous and illegal in many places (for example, {{w|Licensing Act 1872|the UK and Ireland}}). A badly-driven horse can throw off its owner, trample passersby, fall on bad surfaces, and destroy any wagon or carriage it's pulling. A self-driving car should be able to understand road rules, which a horse will not - which is presumably why the cars in the comic and the title text are both specified as being more intelligent than a horse. | Note that riding a horse while drunk is in fact still dangerous and illegal in many places (for example, {{w|Licensing Act 1872|the UK and Ireland}}).
