well actually two. Both predicated on macho (or drunk) individuals relying on the ability of the vehicle design to anticipate danger.

1) Kids following a craze/game of jumping in front of driverless cars to annoy the passengers as the emergency stop software connects. Or worse have the contents of their laps crash to the floor, eg computers. And even worse, injuries like whiplash or badly placed objects hitting them. Kids will only learn by experience, modulated by Darwin's theory.

2) Drivers of normal cars taking chances hoping that the driverless car will always give way. Which relies on human judgement on the part of the idiot driver, and human judgement on what constitutes well developed software.

The point is: driverless cars have that inevitability of becoming ubiquitous and the debate of the consequences have to be debated. We have to predict things so we can't call them that perennial lie "unforeseen consequences". The cost of not doing it is peoples' lives.
