So, because the problem exists in lots of dashcams, it's ok that the A129 Duo does it too?
By that same reasoning, this too should also have been just fine:
(And no, this is not anti-Chinese -- if anything I suppose it's anti-homosapien)

Ozone hole mystery: China insulating chemical said to be source of rise

In a High-Stakes Environmental Whodunit, Many Clues Point to China
Here is the very short version: A couple dozen home insulation producers exist in the same local region, all competing with one another. One begins using CFC-11 to produce its foam insulation product, mainly because it is cheaper, but that CFC-11 is well known to destroy the ozone layer and is illegal everywhere. Because the other producers struggle to compete by following the rules of not using the banned chlorofluorocarbons, they all (except one or two) switch over to CFC-11 to compete on price and stay in business. And they nearly all justify their behavior as acceptable because the others were doing it too. And sufficed to say, we all need that ozone layer in order to live. (Ironically, they were selling a home insulation and simultaneously destroying the Earth's insulation from the ultraviolet radiation.)
Now you may rightly ask, what does this have to do with dashcams? In many cars, the traction control system needs to know how much air is in the tires, so it can properly counter forces and conditions in order to keep the car on the road in extreme circumstances. When electromagnetic interference from the dashcam prevents the tire pressure monitoring system from functioning, many traction control systems will go offline because they cannot operate without proper tire pressure data. In that case,
the faulty dashcam product which is supposed to help prove that we did not cause a car accident,
could actually be contributing to the cause of that accident, when the car's traction control system self-disables because the dashcam is spewing out that all that electromagnetic interference, interrupting communications of the tire pressure monitoring systems.
So we should demand that they all pay attention to electromagnetic interference issues while designing and building these dashcams, instead of simply going with whatever is the cheapest option -- which may very well ultimately affect the life, health, and well being of some of its customers. Are we willing to risk that the EMI spewing dashcams won't prevent our other automotive safety systems from operating properly when we most need them too? How much would it cost to produce properly shielded non-interfering circuitry and/or power supply for the Viofo A129 Duo? A dollar per unit? Maybe two? (When we have the benefit of hindsight, will we see that these dashcams in similar ironic fashion, contributed to some the accidents that they ultimately recorded?)
