I'm not gonna pass a vehicle that is stopped in my lane trying to turn.
Why won't you pass them if they are stopped?
I just don't feel confident in my driving skills.
You should always drive defensively. If you do not feeling comfortable passing, then avoid it.
I'm glad you understand. Lots of people don't like my driving style.
It's always better to be careful when driving! If you don't feel comfortable driving at a certain speed or passing someone, then don't do it. If more people drove safely like you, we would have fewer accidents.
