Unbelievable, isn’t it? The Ponzo illusion works because our brain judges an object’s size based its perceived distance. The 3rd car seems further away, so it looks much bigger. You can take a ruler and measure the heights of the three cars, but even after you ‘know’ that the cars are of the same size, your brain simply refuses to see it that way.
