高1・高2向け｜英語長文問題94（交通）132語＋和訳・解答解説

Autonomous cars are becoming more common, but they still need help to drive safely. They use sensor technology to “see” the road. Cameras watch lanes, traffic lights, and signs. Radar sensors can measure how far other cars are, even in rain or fog. Some cars also use laser sensors to make a simple 3D map of nearby objects. The car also checks its own speed and position with GPS and wheel sensors. A computer in the car puts this information together many times each second. If a child runs into the street or a bike appears from the side, the car can slow down or stop quickly. Drivers must keep the sensors clean, because dirt or snow can block them. That is why engineers test these systems on many kinds of roads.

Which TWO statements are NOT true according to the passage?

1. Cameras help the car notice lanes, lights, and signs.
2. Radar can detect other vehicles even in rain or fog.
3. The car uses only GPS, so sensors are unnecessary.
4. Its computer combines many sensor readings again and again each second.
5. Drivers should clean sensors because snow or dirt can block them.
6. Engineers test self-driving systems only indoors, not on real roads.
