Mobile phone use while doing most anything can result in harm, be it walking or driving or just talking to an X and getting one’s dander up.
Be that as it may, the so-called solutions to every misdeed, danger, possible danger, and supposedly possible danger has been to enact ever more laws with ever more fines. Reality is that the harm rate will never go to zero because humans are what we are.
The costs of surveillance including development, owning, operating, catching, and prosecuting is non-trivial. One may reasonably question how many harm-events are avoided by that versus how many people are caught and fined. Any answer would be conjecture. But as with many of our laws we seem almost unique in the world at legislating anything that does or could cause harm.
In the case of seat belts it seems a clear win; bicycle helmets not so much - while they sometimes save a head they also contraindicate many of us cycling for pleasure or exercise. In Heidelberg Germany a few weeks ago the bicycle parks near stations were epic and some riders had helmets and some did not and some were commuting and some not.
A phone in a hand takes ones attention off the wheel and possibly the street. Is it best to prosecute someone who is responsible for a harm-event who was using their phone (texting, talking, or watching a video) rather than establishing a world first surveillance system whereby there are reports of the cameras confusing chocolate bars with phones?
Talking and especially arguing with a fellow occupant in a car is also distracting as often as not. History has decided not to prosecute them nor legislate against talking excepting for special cases such as P drivers and passengers in some jurisdictions.
What price is legislating everything about everything when the main demonstrable result is revenue for failing to comply with rules, be they well meaning or arbitrary? It is a long used retort ‘if you don’t do the crime you don’t do the time’ but with the numbers of laws, discretionary application of some laws, and technical nature of infringing others and especially those that may not make much sense to a significant part of the community, I wonder why we are happy with it all when the costs-benefits are weighed up.
Is theoretically preventing a single harm-event (eg) per week worth the laws, fines, and imposition on the other 99% 24x7?
Those who use mobiles while driving may be idiots, but ‘we’ do so many idiotic things, often with great enthusiasm and zeal where does (or does?) the government’s hand need to stop?
