Nope. If it doesn’t affect you nor anyone else it’s not a problem by its very definition. But you go and report it. But make sure that every time you see a mtb on a footpath you report that too. Oh and make sure you loop in anyone driving over the speed limit.
I know this isn’t really the thread for this, and many (most?) of you will disagree with me on this.
But yes, speeding is a problem. Driving standards are poor in the country. People in cars and trucks often treat people on bikes or people on foot extremely poorly.
Choosing to drive above the legal limit, and doing so deliberately, is not ok. If it’s not a choice and you haven’t done it on purpose then IMO you shouldn’t be driving at all, because you failed to be in control of the lethal machine you’re in, or be aware of your surrounds – including the current legal maximum speed.
If you’ve chosen to break the maximum permitted speed to save a few seconds journey time then you’re part of the problem of road deaths and near misses.
Not that speed of the primary cause of all crashes: I know that isn’t the case.
But choosing to ignore the rules that make traffic as safe as is reasonable erodes the importance of & attitude to all the other rules – safe parking choices, safe stopping distances, safe use of phones, respect for other road users. If everyone tried hard to be a good driver, obeyed all the rules as best they could the roads would be safer, better environments with likely (IMO) less stress, congestion and harm.
So yes, obey the limits. Choosing to go faster is selfishness, and nothing else. Sacrifice a few seconds of your time to make the potentially lethal thing your doing safer.
Driving is a licenced, insured, regulated privilege that needlessly kills many many people as a result the selfishness, and as a result of the attitude that “speeding’s ok”.
It isn’t. Follow that rule. And the others too.
Be a decent human.
