Line detection, blind spot assis and Distronic Plus, are they worh it?

Hi folks,

I ordered a CLA 220 CDI and I still have a couple of weeks to change the options.

Regarding the line detection and blind spot assist, for those who have it, is it worth it?

Same question for Distronic Plus, is it worth it? especially since by default we already have the collision prevention assist (I know they don't offer the same capabilities, but in terms of safety, collision prevention assist may be enough?)

I'm hesitating to take none of them, some of them (e.g. line detection only) or all the them, but them the price tag is slightly different.

Thanks in advance.
