According to the consultancy firm Chetan Sharma, connected cars made up 32 percent of new connected devices between January 1 and March 31. Mobile phones, on the other hand? 31 percent. Tablets made up 23 percent, while connected devices belonging to the so-called “Internet of Things”—Nest thermostats, smart refrigerators, etc.—made up the remaining 14 percent.

That doesn’t mean cars with built-in cell phone connections have quietly grown to outnumber the 330 million-plus cell phones currently in use across the United States. The data concerns new activations—new devices being added to the networks, not the total number of connected cars (or phones) across the board.
