Got to say this - a great peeve of mine - this is yet another dreadful piece of road design.
WHY - WHY IN THE NAME OF GOD - was your lane designated as a second forward lane when the exit is going to merge into a single lane????
There is no advantage to this. NONE! And - as we see here, it runs the risk of causing collisions. Why do they do this?
Also ... the use of a forward arrow to show that you're supposed to turn left! Genius!
Road planners are idiots. I think I'll make this my new signature.
P.S. I've mentioned before that I avoid overtaking on roundabouts. Your video is an excellent example of why. Virtually no benefit, plenty of risk.
