The Passengers by John Marrs

Eight self-drive cars set on a collision course.

Who lives, who dies?

You decide.

When someone hacks into the systems of eight self-drive cars, their passengers are set on a fatal collision course. The passengers are: a TV star, a pregnant young woman, a disabled war hero, an abused wife fleeing her husband, an illegal immigrant, a husband and wife - and parents of two - who are travelling in separate vehicles and a suicidal man. Now the public have to judge who should survive but are the passengers all that they first seem?
