You posed a question and I answered it:
Why would you want to remove headrests and also why would you want to shut of daytime running lights? I'm just curious to see what the reason is...and if it's something I'd wanna do
You specifically asked why, seeking reasons. Right?
It's not a "tirade", it's just my stated opinion as to what my preferences are, explaining "why". There is no reason for you to take things personally. If you ask a question in a forum, be prepared to tolerate the opinions of others - especially when the forthright response given was in answer to your inquiry.
