All of this takes a minimum of 6 months of constant effort to develop.
Other things:
Avoid riding in the center of the lane in town, particularly at intersections. Lane centers at traffic signals and signs tend to be very slick in the rain. Although I ride mostly in the left tire track, I occasionally shift to the right for a bit. I think the change in position helps car drivers' attention.
For that matter, just after a rain starts, the water can bring up the road film making the pavement slippery. After it has been raining a while, the water will wash the film away.
I see a lot of accidents here in Saudi Arabia, many caused by simple stupidity. At an intersection where you have two left turn lanes, fender benders where the car in the inner turn lane makes a left turn and the car in the outer turn lane makes a U-turn are pretty common.
Wet leaves on the pavement have an unpredictable effect on traction. So do painted lines.
Get in the habit of always using your turn signals even without traffic around you. If you always use your turn signals, you will not forget the one time where it will be very, very important.
As for turn signals on a car, all that the signal tells you is that it works.
In a lot of places (El Paso, TX comes to mind), turn signals are just decorations on the corners of the cars.
