Maybe the robot thinks: Heck, if I'm gonna crash, may as well crash into the safest place to do it. At least they can rescue me/put out the fire/solve it somehow. Or to take a leaf from the film I, Robot:

  SPOONER:

  The truck smashed our cars together...

  and pushed us into the river.

  I mean, metal gets pretty

  pliable at those speeds.

  She's pinned. I'm pinned.

  The water's coming in.

  I'm a cop, so I already

  know everybody's dead.

  Just a few more minutes

  before we figure it out.

  An NS-4 was passing by...

  saw the accident and

  jumped in the water.



  [flashback]

  NS-4 ROBOT:

  You are in danger.



  SPOONER: Save her!

  NS-4 ROBOT: You are in danger.



  SPOONER:

  Save her! Save the girl! Save her!



  [realtime]

  SPOONER: But it didn't.

  It saved me.



  CALVIN: The robot's brain is a difference engine.

  It reads vital signs. It must have calculated...



  SPOONER: --It did. I was the logical choice.

  It calculated that I had a 45

  percent chance of survival.

  Sarah only had an 11 percent chance.

  That was somebody's baby.

  Eleven percent is more than enough.

  A human being would have known that.

  Robots, nothing here.

  Just lights and clockwork.

  *Go ahead and you trust them if you want to.*
