Irresponsible Drivers

There is a very interesting intersection at the bottom of the hill from where I live.
It has always been a bit of a problem.
Once, coming from the side street, one had to cross 8 lanes of traffic to get to the outside lane on the other side. There were no lights there at the time.
Now!
There are lights and their signals go through, Straight Through, Alternate Left turn. Alternate Right [on either a u-turn is allowed], rigtht to left/left to right Straight Through.
There is also from one direction, a left turn with caution.
Well, for starters, the left turn with caution is already a problem and the renewed intersection is only months old.
Lights need to control the left turn as the Straight through left/right is already proving dangerous to drivers.

Another problem at this intersection, is the factor of not signalling the left turn prior to arriving at the turn.
Many cars are going straight ahead and are using the WRONG lane.
Counting one night, 7 out of 12 cars did not give any form of indication in any of the various direction combinations.

Wake up Queensland drivers, you are a danger to yourselves.
