Google's self-driving car was just involved in an accident that seems to have been its fault

There's a reported accident that took place on El Camino Real in Mountain View that involves a Google self-driving car and a public transit bus.

Google's self-driving car was trying to merge back into a lane and it thought the bus was going to let it in. The bus had no intentions of letting the car in and it ended up doing damage to the left front fender, the left front wheel and one of its driver’s -side sensors. The car was going 2MPH while the bus was traveling 15MPH and no one was injured.

Computer thought: It'll be fine so long as I pull out in front of this bus slow enough. It will see me and let me in.
Bus driver thought: LOL nope.

I read that Google already corrected the algorithm at fault. It was in the glorious optimism subroutine
