Most European cities where scooters (mopeds) make up a seizable portion of traffic (e.g. Paris) would come to a standstill if you "didn't do that".
The issue is more that drivers in the US aren't used to sharing the road with these vehicles.
In Paris, drivers naturally drive far left and far right on roads that have two lanes per direction to leave a corridor for the scooters in the middle.
Then 'going around traffic' is less of an issue for everyone involved.
lane spitting is mostly illegal in the us, but a legal thing in california. so here, in dead stop traffic, you in fact can do that, and it doesn't involve weaving in and out of traffic. calm down.
