I am asked of this question many times, and most of them are driving very confidently now, so what can change driving confidence?
Actually our confidence should be based on solid driving skills. If your skills level have not reached the advance level required by the driving test, which reflects the needs for real life driving, it’s quite OK not to feel confident yet. If confidence level over skill level it can be dangerous, many news headlines are telling us this truth unfortunately.
So the way out is to focus on improving the driving skills to the required level, e.g. you can change lane by yourself with traffic, you will feel more confident in driving naturally.
