I didn’t ask for your help other than accepting other opinions exist. In some cases the distinction is of high value. In some cases it’s at low cost. I’m of opinion this is low value and high cost, thus the cost benefit analysis fails. You’re free to disagree.

Cop uniforms are low cost and serve a significantly higher purpose. Taxis being a distinct color is unnecessary too. If I can identify a Dominos delivery vehicle from a distance, than they just need to try harder with their lit signs. A simple redesign could render vehicle paint job obsolete. Just because it’s been that way doesn’t mean it is the best or only solution and it certainly doesn’t mean it has to remain that way.

Perhaps you don't understand how HN works. When you give an opinion, other people can disagree.

If you don't like what they say, don't complain that you "didn't ask for their help". If that's your attitude, perhaps internet forums are not the place for you.

Telling someone "If you don't understand this, I don't know how to help you." is unnecessary snide that I was addressing. It is an passive aggressive attempt to assert your opinion as the only valid opinion.

> Perhaps you don't understand how HN works.

You continue with unnecessary attempts at belittling, while thinking you're in the 'right'. Perhaps take your own advice regarding internet forum usage.

> When you give an opinion, other people can disagree.

Yes, I'm disagreeing politely. You're the one having trouble accepting it.
