About 50% of truckers in the US are owner operators, meaning about half of all truckers on the road own their truck and as such buy (electric) trucks and quote for jobs.
Companies are in the business of making money, if a private contractor is cheaper (and faster) than their in-house logistics who do you think is going to be axed?
I've had unlimited free texting in western Europe for over a decade now, and so have many other western Europeans. I've had unlimited free texting for longer than I have had unlimited mobile data, yet I still use WhatsApp, I even used WhatsApp back when I didn't have free unlimited mobile data.
It's not about free texting or not, IMO it's either about mobile data or laziness.
