| 摘要： | The 'idea' of self-driving vehicles has been around since the 1960s. As a tractor-mad child I watched horrified a black and white film of a driverless Massey Ferguson 135 tractor steering its way between the trees of an apple-orchard while it sprayed the blossoms with DDT. Leaving aside the non-benefit of spraying insecticide on a crop depending upon insects for pollination, it was pointless technology, as the tractor was following a wire buried in the ground and any attempt at using it for a cultivation task was doomed to a rather obvious failure. Things have moved on since then, and the arrow-straight rows of maize we see in the fields are a result of tractors steering themselves with the aid of GPS, while the human driver just turns the thing around on the headlands and checks the flow of seed and fertilizer. The skill to sow a field with rows so straight you could fire a rifle down them is no longer a priority for farmers, just as handling an Eaton Twin-Splitter gearbox is no longer a sought-after ability for truck drivers. |
