There isn’t really a universal answer. Different companies have different objectives. Some of them sell it to third parties, some of them use it for a variety of business purposes. Some of them collect and store it without any idea what they are going to do with it.
I actually worked for a company that did this. They’re a commercial and industrial vehicle OEM. A lot of their hardware interfaces with the vehicle CAN bus (the computer network on all modern vehicles). They would vacuum up every message broadcast on the CAN bus and dump it into a data lake while having absolutely no idea what they were going to do with it.
