THE OUTLOOK: General Motors Corp. says that within the next 10 years it should be able to produce a car that drives itself. Other car companies and parts suppliers are working on similar systems.
HOW THEY MIGHT WORK: The plan is to use an inexpensive computer chip and an antenna to link vehicles equipped with radar-based cruise control, lane change warning devices, electronic stability control, satellite global positioning systems and digital maps.
POSSIBLE EFFECTS: Such a system could prevent crashes and reduce congestion. Government regulations, liability laws and privacy concerns would need to be addressed.
