I have a 2016 Hyundai Tucson. To obtain the traffic camera alerts, I need to tether my phone to the car. The car then uses my phone's data connection to obtain the latest traffic updates. However, whenever I drive out of my home country, which is quite often as I live in Central Europe, I turn off my phone's data connection. Otherwise, I'm slugged with a big bill for data roaming.

If I had to use the phone's data connection for, as an example, the entire navigation system, it would seriously degrade the experience once I'd left the borders of my home country. As it is now, I already lose the convenience of traffic camera alerts.

I appreciate there are options - OsmAnd with local maps, a better data roaming package or simply rely on paper maps. Nonetheless, I don't believe relying entirely on the phone for in-car functionality is viable until data roaming has been addressed.

Not true.

If you buy a commercial display (you know, those panels you see in airports) not only will it be a far higher quality display than any consumer model, but it will also be the dumbest display you can imagine.

They're not that much more expensive - which makes sense, since end users are sometimes building video walls out of 10 or 12 or 16 of them ...
