technically indeed, in practice it's much more complex / nuanced and is being discussed, reported and proved on this group almost every day. You're only focused / blinded on one thing and you thus keep contributing with useless comments despite people already telling you that your argument is laughable.
you're right, safety first ❤️ You don't wanna ride like many here on the road 😁🫣 Not many things are different at the end (Well accept riding on the left, takes some time to get used to). For the specific road signs and rules you can find good reads / websites online explaining it into English. DLT has the "online course" you have to follow, check it out. Some infos in those videos.
