Alternate timelines ATL

We often wonder how things function in aleternate timelines. Are their GO lights instead of STOP lights? How about ORANGE HALT SIGNS?

Yes, we may find other timelines that look a bit "funny" to us, but to them we are the weird ones.

Each ATL is like a snowflake slightly different than all others, and yet some are so close to ours the you can hardly tell the difference.
