I understand what is driving
I understand what is driving the elimination of 2G and 3G technologies. And I understand that this is outside the vehicle manufacturer's control.
What I don't understand is how a manufacturer of a hard asset, such as a vehicle that has an expected life-span of 15 plus years, does not have a method to provide a modification to support eventual changes/upgrades for communications systems.
This is as simple as changing from one cell phone to another, not replacing an entire car.
If I have to replace my car as often as I have to replace my phone, then this is a failed approach, and the manufacturer that recognizes this will get my business in the future.
What if, perchance, the government were to suddenly decide that 5G is unsafe, and banned it for personal use? Suddenly, hundreds of thousands of vehicles would become similarly impaired if manufacturers had no method in place to provide a modular change to their vehicles.
