The fact that the CAN bus is not wireless is rather a feature in terms of safety.
On the one hand - and thank God; routing car controls over networks by default sounds like a tremendously bad idea.
On the other hand - while a lucky accident in case of cars, modern electronic devices also don't have these, but for different reasons. When was the last time you could make your phone call people and send text messages over wireless connection, via an API built into the phone? Last time I remember being able to easily do it was in the feature phone era.
Modern hardware is increasingly controllable through hidden, restricted, undocumented APIs, or public APIs that require installing third-party software, go through third-party servers, and involve signing some contract or accepting some ToS. That same API-providing-software then proceeds to exfiltrate any and all data it can get its hands on. I do not want any of that in a car.
Is it ironic that this post was posted using tcp/ip dating from much before 1986.
Yes, it would be nice if it was open sourced or documented outside obd2 interpreters. (Though much of it is documented for an industry insider paying fees) or if it openly supported higher bandwidth.
No reason why a 20'x8' low voltage system needs wireless, especially given that similar systems often exist < 1' a way.
What kind of "car technology" are you talking about? It sounds like you're talking about traditional tech, not tech that increases the ability of the driver on the road.
Every single GM, but who is counting. And I bet other manufacturers as well.
It feels like car technology stopped when the generation of those born in the 40's retired. Ever since then, younger generations have been focussed on the internet, computers and phones, and the car has become a tool like a pencil - it works well enough, and new models only see incremental changes.
