　　(2016·山东省实验中学一模)I passed my driving test at the fourth attempt. You might think that means I'm not as safe as someone who passed on their first attempt. But would you feel safer with no driver at all? Maybe not, and that's why automotive firms have included driver­assist functions in their driverless cars. This allows the human driver to take over if there is a problem.

　　Google is one producer that has prototype driverless cars. These cars have been newly equipped with auto­steering wheels and conventional controls to allow normal driving. But this is just a stage — the vision is to have fully automated cars very soon. The director of Google's self­drive project, Chris Urmson, hopes his 11­year­old son will never have to take a driving test. To achieve that, the cars need to be on the roads in five years. He says driverless cars will greatly reduce accidents and traffic jams.

　　According to Chris, about 1.2 million people are killed on the roads around the world each year. That number is equivalent to a jet falling out of the sky every day. He thinks gradual changes to existing car designs are not enough to deal with the problems. “If we are really going to make changes to our cities, get rid of parking lots, we need self­drive cars，” he says.
