What’s more: wires cost money that car companies would rather not spend; add weight to the vehicles, affecting their performance and fuel economy; make assembly more challenging; and ratchet up the possibility of maintenance issues. So, now the aim is to get rid of most of the wires snaking through a vehicle. And in a time when Wi-Fi, Bluetooth, and cellular communications are ubiquitous, it seems only natural that car companies would solve this problem by going wireless.
