Dangerous Cape Town drivers

This last weekend I observed two incidents where drivers in Cape Town were driving dangerously.

One case was as follows:

In the 80km/h zone on the N1, I moved one lane to the right while keeping a good following distance to the car in front of me, but not big enough to fit another car including a good following distance. I was driving just under, but close to the speed limit.

The next moment a car was trying to squeeze into the gap in front of me, but coming so that our cars would collide. The car was also not using indicators. Shortly after this the car was rapidly changing lanes and driving much faster than other cars.

At the traffic light ahead with the left turn that same car was yet again pushing others to the side. They mostly moved to prevent accidents. A bit further ahead after the turn on Oswald Pirow street, I caught up with it at the traffic light.

Once the traffic light went green every car started moving except for that one, which took a while to start. When it finally started, it went speeding up the bridge ahead that goes over the railway tracks and past Cape Town station to the traffic light with Good Hope Centre on the left.

That traffic light has two lanes going right which end up in two lanes. The traffic light was red and that car was on the right lane and another one on the left, both wanted to turn right. When the traffic light turned green, that car started to change lanes in the turn on to the left lane and forcing the car on the left lane to brake to prevent a collision. After this it started speeding up and I lost track of it because I was still approaching the traffic light at a distance which was about to turn red again.
