Yes, and an NYC cabbie would _never_ willingly ignore a regulation like that.

I acknowledge your sarcasm, but indeed they rarely do. It's happened to me only once, and it was fairly easy to report them to the TLC.

I don't know a single city where license numbers and the complaint hotline are so prominently placed as in NYC. I believe it was common that cabbies ignored regulation but this appears to have changed in recent years.

But there's a legal sanction for doing so; it's a condition of their license.
