It uses Bluetooth, not Wi-Fi.

Yeah sorry about that. I actually know it's Bluetooth and not Wi-Fi, but I was just working on my Wi-Fi in the house before I posted that comment, so it got stuck in my head. I connect my phone to my stereo system in my car via bluetooth.

But there are a ton of factors that make wireless communications less reliable than wired.

Over long distances, sure. But in a vehicle, with that short of a distance?

It would have to be one hell of another thing interfering to break a Bluetooth connection in a car.

I have an irrigation valve that turns the water on and off for the garden. It talks to the app via Bluetooth, and I've found that my phone has to be at least 3m away from it or it won't connect. Any closer and the signal must overload it to the point where it can't interpret it. The first one I bought, I took back to the store and swapped it for another before I figured out what the problem was.

I'm sure it's a bad design on the valve's Bluetooth implementation, but nevertheless, it exists.

I have an irrigation valve that turns the water on and off for the garden. It talks to the app via Bluetooth, and I’ve found that my phone has to be at least 3m away from it or it won’t connect. Any closer and the signal must overload it to the point where it can’t interpret it.

Not to discredit your example, but that's not exactly a car that we're talking about right? I would imagine more due diligence would have been done on the engineering side for a Bluetooth connection in a vehicle, versus a lawn sprinkler.

If cars were having that same problem of close distance issues that would be making the news, especially if it was a whole fleet of cars that that problem was happening for.
