Revenue is less important than profits, and car manufacturing is generally a low-margin business. Meanwhile SpaceX' Falcon 9 is the cheapest rocket (something like $70m/launch), while the cost to SpaceX is $10-20m per launch. So there's 200%+ profit margin. Starlink doesn't have any real competitors now, and fast internet access in sparsely populated areas is a big market (also with big money from military uses). Most of SpaceX revenue is from Starlink.
