I used to work for a well known automobile company as both an employee. I've also worked for other auto companies in as part of a consulting job. Auto companies are typically big, slow, and focused on selling a product that takes years (e.g. 3+ years for mid-model refresh, 6+ years for new car model) to take to market. Decisions are very consensus based because all decisions (even marketing) are longer term decisions.

All of that is reflected throughout auto companies. Even the latest technology such as telematics for predictive maintenance and electric charging are highly dependent on the market, suppliers, and government forces that drive infrastructure changes.

The IT org and most technical jobs exists to support that slow moving structure. If you are the person who wants to move fast and be entrepreneurial you are probably going to struggle in an auto company. Just something to keep in mind as you decide if you want to stay in a job or start something on your own.
