Note how much ink is used to target Tesla as opposed to Pappa's. The real reason that Pappa's is being sued under the Dram Shop Act is to destroy complete diversity, so as to avoid removal to federal court. If they only sued Tesla, they might get taken to a less sympathetic federal court. By including a Texas defendant, Tesla can't take them out of a state court that may very well be far more sympathetic to local police, or simply more plaintiff-friendly in cases sounding in negligence or products liability.
