I’m sure y’all are great bad asses who know these roads like the back of your hands and can navigate them with your eyes closed while your speed around like Big Bear is between Paris and Dakar.
But for the love of god, drive on your side of the street! Some of us have a plan to stay alive and in one piece. Thanks.
Ps. While I’m here, if someone is already at a round about they have the right of way, no matter what street you’re coming from.

How does it work? I understand Dragon riders have an advantage against all other people being able to fly distances quickly that for others would be days long carriage rides. Having that said, how are people in Dragonstone warned about someone living in a Dragon from kingslanding before that person arriving at their destination? Through the series there’s been many episodes like this where people are quickly messaged about things. Is this explained in the books? Was it covered in the show and I didn’t pay enough attention? Is it just some poetic liberty that I should accept to enjoy the story and not think too much about?
