If science fiction shows and movies from decades ago were to be believed, by 2020 we’d all have jetpacks, butler robots, and autonomous cars that flew us from place to place. And, while many of those wilder fantasies are still just that, the world is getting closer to futuristic vehicle technology that looks like it’s part of a sci-fi novel of its own.

                  A big player on this stage is the company Tesla, run by eccentric billionaire (and previous driver of the first car in space) Elon Musk. While their electric cars, like the Tesla 2 and 3, have been around for years, the company made waves in November when they announced the forthcoming release of their pickup, the blocky-looking Cybertruck. But a lot of people don’t realize that years before that, Tesla was in the news for a different truck on their list, which is due to arrive by the end of this year. Have you ever heard of the Tesla Semi?

If you’re reliant on your vehicle to work, one of the most frustrating events that can happen is your engine not starting when you need it to. You could have sworn that everything was checked out, that your battery was still pretty new, that it hasn’t been that cold outside lately…so what’s going on? Well, you might be experiencing a phenomenon known as parasitic power draw.
