OTA Updates
OTA Updates (Over-the-Air Updates) is a modern way of updating software in vehicles, similar to how smartphones receive updates. Instead of taking a car to the dealership, new features, fixes, and improvements can be downloaded and installed wirelessly. This technology is becoming increasingly important as modern vehicles rely more on software. Companies like Tesla have made this approach popular, and now most major car manufacturers are adopting it. It's sometimes also called "remote updates" or "wireless updates" in job descriptions.
