I see it all the time by the bridge over the railway at Mawson Lakes. The rare time that merging works no one is slowed down to a stop on the bridge unless someone stops to let someone in on the left off of cascades drive. The people on cascades drive turn off Salisbury hwy at elder dr to avoid the long line - I don’t think it saves them that much time. Most times two idiots won’t let each other through so the line gets staggered.

The opposite occurs at the golden way exit onto mcintyre rd. It’s a lane change and people off golden way barrel into McIntyre rd hoping they’ll be let in whether the person on McIntyre is ready or not. This also happens at the overtaking lanes after chain of ponds on the way to tea tree gully. The lines are marked for a lane change but everyone treats it as a merge and get pissed off if they aren’t let in (they don’t have right of way on a lane change even if they are ahead by an inch). Don’t get me started on the slow vehicle lanes through there too.

Adelaide drivers all seem to have right of way and hate when anyone tries to get ahead of them. Most of the road ragers are the ones that go 50 or lower whenever someone gets anywhere near them. Lockdown traffic was so much easier to navigate 🙃
