Tesla owner Andy Weedman discovered that his Tesla was registering a giant stop sign printed on a billboard as a real traffic sign, and so halting in the middle of the road.

Weedman tweeted and recorded a video of the Tesla stopping for the billboard, referring to it as an 'edge case'. 

Others went further, arguing that 'the world is absolutely crammed with out-of-the-ordinary situations we call edge cases,' and that it will 'likely take more than patchwork updates and fixes to actually reach full autonomy'. 

The discovery prompted commentators to observe that autonomous cars have a long way to go before they are truly fit for purpose.
