Yes, the red line *should* mark the position of the maximum effect (mark facing straight down or up). I have several of these CPLs and they were always spot on using this mark. So simply hold the filter in front of you you and put a piece of paper on the dashboard. Look through the filter and as you rotate it, paper should be more/less visible in the glass, and the least when red mark is facing exactly up or down.
Your picture seems perfectly fine to me, you will NEVER remove 100% of reflections, and it does not have to be necessarily worse than the first picture you posted, it is just different lighting that changes the composition completely.
Simple test is also to remove the filter and check again on the same route/time of day/lighting conditions, and you will see the difference clearly.
