One of Google's self-driving cars crashed into a bus in California last month. There were no injuries.
It is not the first time one of Google's famed self-driving cars has been involved in a crash, but it may be the first time it has caused one.
On February 14th the self-driving car, travelling at 2mph (3km/h), pulled out in front of a public bus going 15mph (24km/h).
The man in the Google vehicle reported that he assumed the bus would slow down to let the car out, and so he did not switch to the manual mode.
In a statement, Google said: "We clearly bear some responsibility, because if our car hadn't moved, there wouldn't have been a crash."
That said, our test driver believed the bus was going to slow or stop to allow us to merge into the traffic, and that there would be sufficient space to do that."
The company's self-driving cars have done well over a million miles across various states in the US, and until now have only reported minor accidents.

Thousands of bees left a town after landing on the back of a car when their queen got stuck in its boot. Tom Moses who works at a nearby national park, noticed a “brown patch” on the back of the car after the owner parked it to do some shopping. When he looked closer he realized it was a huge group of bees.
Moses said: “I have never seen that many bees in one spot. It was very unusual. They were very close together and there was a lot of noise and movements, it was interesting to see such a strange sight. But there were a lot of people around and I was a bit worried about the bees and the people stopping to look. I thought that someone might do something stupid.
Moses called two local bees specialists who helped removed the bees by attracting them into a box.

The snake has been named silver boa because it is metallic colored and the first specimen found was climbing a silver palm tree.
