I was actually thinking about this this morning in traffic. Ive been noticing more some drivers that edge closer to the middle line, with the look to jump lanes. Head checking the mirror, almost as if they are ready to pounce on an open spot. Then one appears and they indicate for like a second and change lanes.
Why not put indicator on earlier to allow people to make room so you can move in? Because it appears that in Cape Town anyway, if you indicate your intention to change lanes, cars in said lane actually speed up to prevent them pulling in. So to avoid that happening, dont indicate, people then seem to be oblivious to the gaps they create. If they know someone is looking to poach it, they wont let it happen. Selfish cape townians..
