How many ‘corner case errors’ do human drivers have?

1 min read

Research conducted in the US has concluded that software for autonomous cars has ‘thousands of unique incorrect corner case behaviours’. The work, conducted by academics from Lehigh and Columbia universities, used a system called DeepXplore, which is said to enable automated white box testing of such systems.

The team notes that a typical autonomous car system will recognise an image of the road ahead by running an analysis through its complex logic system. This process largely occurs in a black box and is not fully understood by anyone, including a system’s creators. Any errors also occur in a black box, they continue, making it difficult to identify and fix them.

Should we be surprised? No. Should we be worried? Probably not.

A couple of years ago, the Electronics Design Show Conference featured a session on autonomous vehicles. A question from the floor asked those in the room who had not written software with errors to raise their hands – and none did. The bottom line is that no software is going to be perfect.

But let’s contrast that with a human driver. Autonomous cars are expected to improve road safety, even with inherent software errors, which makes you think we have many more corner case errors in our ‘software’.
