Can cellphones handle vehicle-to-vehicle comms better than radio networks?

It's going to be a long time before DSRC-equipped vehicles are common on our roads.

Within a couple of years it will be impossible to buy a new car without an embedded LTE modem.

Using the modem in your phone connected via Android Auto/Apple Carplay/Bluetooth this might be a good idea. If it's an extra $20 to give your predatory cell company an extra line for your car it'll never get mass adoption due to the recurring cost.

Using an external modem or a longterm baselined protocol instead of an in car modem is also needed for longevity. US cars have a >20 year lifespan, the feds can mandate a car only standard that lives that long; your cell company won't maintain its legacy networks that long. 20 years ago was 1g analog (shut down about a decade ago) or maybe 2g which is in the process of being shut down now. The successor 3g networks are going down almost as fast and will likely have an even shorter total lifespan.

As I understand the rules I can all but guarantee this is illegal in California right now. They take a dim view on electronic devices attaching to the windshield (it looks like they've added a strict GPS in the corner exception now), and phones anywhere above the dashboard line. Which is kinda a shame.

Not seeing how that's any different than a GPS? That can't go in the corner because I'd have to hold it vs putting on the flat part in the center. Plus its absurd to argue its "obstructing my view" when I can see my own hood over top of the phone/GPS.

Then again, I guess it is CA where everything gives you cancer so I suppose that's somehow logical.

I guess they want you to clip your phone to your air vent, where it's low enough you need to take your eyes off the road to see your map/etc. :eyeroll:
