All automobiles are supported by an ecosystem of services, which traditionally includes dealerships, repair shops, and fueling stations. One of the ways Tesla has redefined the auto industry is by vertically integrating these services. You can buy a vehicle directly from Tesla, have it serviced at a Tesla service center, and charge it at a Tesla Supercharger. On the whole, most customers seem to be happy with this arrangement, but some believe that there is an unmet need for independent repair shops, and a community of DIY Tesla repair techs has developed. Because Tesla doesn’t support their activities, there’s an underground, hacker vibe to the scene.
