Your acceleration could use some work. You might not be giving yourself enough time to pull out onto roads or you might feel pressured by other drivers - but this video will help you improve.
A few acceleration tips
Wait for a large enough gap in the traffic so you don't have to accelerate harshly to move out the way of other oncoming traffic
If you don't read the road well enough you might be having to put your foot down to get out of danger
Make sure you're allowing enough time to pull into traffic and watch the road up ahead as you approach junctions
