you don’t even need bluetooth. there’s license plate readers on all highways which feed into traffic indicators on apps or those road signs that say how many minutes away places are

License plate readers are costly and need to be positioned with a good field of view etc.

Bluetooth sensors are more widely used, you've just never noticed them.

Also, the highway congestion is most likely done with magnetic inductance loops.
