announced its Origin. It is intended to act as a shuttle service(班车) that drives itself. You can call Origin through an app and get to where you’re going, but you never need to own a car again. That’s the idea, anyway.
Origin shows some promise. For one, it is not made to be sold to consumers. It is, rather, designed from the ground up to be part of a so-called “ride-sharing” service. By making the car modular(模块化的)and upgradeable, Crusie believes it can bring down the exorbitant(过高的) unit costs of self-driving cars.
But Crusie and other self-driving companies that claimed that they’re the future of how we get from point A to point B face some serious problems, some technical. Firstly, autonomous driving doesn’t actually seem to be ready for the reality of messy, complicated streets that are full of humans. Most experts now agree that full self-driving tech is far from ready--- and in fact, may never be ready. Yes, it’s true; the company Waymo has put autonomous vehicles with no safety driver into service. But its pilot project is taking place in a suburb of Phoenix, Arizona, an almost ideal test location, with wide streets, low traffic, and minimal pedestrian(行人) or cyclist presence.
Further, self-driving cars face another problem of their own making: Their various sensors and safety technology are actually making human-driven cars safer. As just one example, automatic emergency braking has already reduced rear-end collisions (追尾) by 50 percent, and the National Transportation Safety Board believes this figure will eventually rise to 80 percent. It seems that avoidant technology, combined with the knowledge of a human driver, is a better solution to the problem of collisions and injury than cars that just drive themselves.
While high tech is playing a major part in our daily life, which makes us more convenient. However, it still has a long way to go. Cruise’s plans are indicative of the problem with self-driving startups. They assume that smarter cars are the solution to our transportation problems, when in fact, a vastly more promising and alternative
