Is there any way to make a stop sign, because there is a traffic light i was just wondering.
What is a "stop sign" ? Nothing can pass? Or a sign that gives priority to some roads at crossroads?
I think the latter. In certain cases it would be useful, but i'm afraid it's not possible without code changes.
The good news is that traffic lights could be set for 1-second in both directions. Not quite the same, but would be very very similar...
