Hope to see AI-driven vehicles in the future
In more ways than one, artificial intelligence plays the driver’s role in an unmanned bus. The reactors installed at the front and sides of the bus collect information from road signs and objects, send it to the central processor, which then makes judgments and controls the bus.
AI could be a “better driver” than humans because its reaction time is much shorter than human’s. When something appears on the road, it can make a judgment in milliseconds, or onethousandth of a second, whereas it takes the human brain at least 0.1 second to react. Also, AI never gets tired and there is no fear of it driving under the influence, and thus it could be more reliable than human drivers.
However, the test in Shenzhen was conducted on an experimental road. And there are much more uncertainties on real roads, such as rash driving by some people.
The biggest problem for AI is not in learning to recognize road signs, but in taking instinctive action during emergencies. So safety and security must be taken into serious consideration before allowing AI to take full control of a bus on a normal road. That problem may gradually subside with more AI-driven vehicles plying on normal roads.
Besides, when two humans drive too close to each other on a road and one has to slow down to avoid an accident, both could expect the other to do so, and the problem could aggravate because they cannot talk to each other. That dilemma will not arise with two AIdriven cars because the two could “talk” via the cloud and decide which one should slow down. Hence, we can hope to see cars and buses are driven by AI in the not too distant future.
