Ok dumbest comment of the year goes to: "Where possible, the keyless entry should be permanently deactivated."
That firstly, negates a good R20k upgrade you took on your car unless it was factory fitted (which is becoming more popular) and then also defeats - convenience opening, diesel-pre-priming in very cold weather, automatic trunk/boot opening or foot-wave opening etc and probably vehicle profiles - so when someone else uses the other key the car won't know to set their preferences on the mirrors, seats, lighting, media etc.
Secondly, we want to make progress into the future, not go back to 1996.
The faraday bag is ok but also just a pain.
What we need is for vehicle manufacturers to simply make it harder to steal the car - but the problem is this is very specific to certain markets i think? They could switch to having an additional factor of auth whereby the key does its thing but the doors will not unlock nor engine start if your paired iPhone or Apple Watch are not also within proximity of the car for example...(and with Apple Watch you can also check if its being worn and authenticated not just lying in a bag)
There's many ways to solve this but i don't know if it will get the focus it needs from vehicle manufacturers because they prob just don't see it as a major problem?
