Low tunnel at Shibaura, in Tokyo
This tunnel is very low and taxi drivers are very unwilling to run through the tunnel. A taxi with only a guest will not pass through it but the car with three can pass through, because the added weight slightly make the car go down.
By the way, excuse not for sharing photos for a long time. I am back and the browser has come to. From now I will upload photos as usual. Thank you for your patinece.
