Nay, I think when you're regulating how what people can say that is just not allowing for freedom of speech.
When I saw this bill for the first time I was aware that the clause "... using profane language that is audible to other motorists" might be the most problematic part of the bill. However, I understand that there are big differences between the US - the home country of most Atlasians - and the part of the world I come from regarding the use and acceptance of profanity. Since profanity seems to be frowned upon in public settings in the US I came to the conclusion that this clause may be appropriate here.
I essentially agree with what citizen Tmthforu94 said about the bill a few days ago:
Other than these nitpicks, I'd be leaning towards this bill.
