I've sent an enquiry that was half a complaint already. I also mentioned I don't expect drivers to pay less attention to the road/tracks, but I don't really see how this could realistically be enforced. And if it can't be then I really don't understand why they even bothered to make this rule/law to begin with.
Maybe I just live in a rough area, but loud phones and people littering and misbehaving is literally a daily occurrence here.
