They may still seem like something for the future, but driverless cars have just taken a huge step forward in safety.
Until recently, self-driving cars had trouble detecting things like road signs in rain or darkness. Researchers have now taken inspiration from humans to help cars see in the dark by picking out features such as shapes, symbols and numbers. Putting these together helps the cars to detect signs and work out what they mean.
Even though driverless cars can now see better, I'd still be nervous about getting in one!
