We can agree to disagree. IMHO, this should be as simple as two settings.

One on the phone: Provide Internet Access to Car: ON/OFF

One in the car: Get internet access from: CAR <-> PHONE


As to the typical driver being challenged pairing his mobile, frankly, I’m challenged
with that on many occasions, not because I don’t know how to do it and not because
I don’t understand what is involved or can’t follow directions, but because BlueTooth
pairing implementation on most cars and most devices is a steaming pile of poorly
written and even less well tested code that is fragile, buggy, and unreliable.

Assuming that the underlying connectivity code works, the above two settings
should not be difficult to implement correctly. They are far less complex than
Bluetooth.


/ I think another thing to remember is that "enablement" can imply a default. For example, if my car comes with a SIM slot, and I choose to put one on in it, then I've implicitly chosen that the car should by default use the connectivity provided by its own 3/4G connectivity. I'm also have likely to have chosen the particular SIM and its associated usage plan based on my expected usage of the Internet by and possibly in the car. If the car also has a Wifi hotspot in it, I'll likely associate my phone with it once, so that from then on my phone will automatically use the car's connectivity every time I get in it, without any intervention on my part at all. That would be much more convenient than having to switch on and off hotspot support on my phone each and every time I get in the car - and it is likely people will sometimes forget, and then try to do that while they're driving, which will be as or more dangerous than sending text messages while driving.
/ Having choice can be good, but you want to try to minimise both the amount of choices and how often people have to make them - too much choice can lead to paralysis, such that making no choice becomes the safest "choice".  I think when it comes to usability, predictable and expected defaults, and matching peoples' existing conceptual and mental models are much better. The book "The Design of Every Day Things" is an excellent book on making things easier to use.
/ Regards,/ Mark.
