One more thing about car phones is there are some of us have jobs that absolutely depend on being able to talk on the phone and be available to talk on a moment's notice in order to earn our income. I work for multiple real estate lenders, title companies, and loan signing agencies. My income is 100% tied to being able to respond to my phone to accept/decline job offers from them to go to client homes to finish and close their loans or refinances as a closing agent. If I couldn't respond to my phone I'd receive zero jobs since they have not already been assigned to me, I accept them when offered if terms are mutually agreeable. And such offers normally go out to multiples of me at the same time, first to respond gets it. Without my cellphone close at hand I'd be done for, income-wise.

The customer most of my work is done for has an annual revenue about 10,000x that of my company. When a problem in the refrigeration system spoils 25% of the refrigerated product in one of their stores, they bill whoever they can blame it on, and that company pays it if they want to keep the business. A delayed response could fairly quickly turn into a bill for my employer comparable to several months of my salary.
