The Texas Dealerships have a very strong lobby, contributing to state legislator campaigns, and able to have strong influence over legislation that's considered when the Texas legislature meets every 2 years (for 4 months). The only product you can't buy in Texas today on Sundays is sold at the dealerships, who've successfully blocked any attempts to allow them to open on Sundays.
Tesla's attempts at getting approval for direct sales in Texas have been blocked every two years by the dealership lobby. However that hasn't prevented Tesla from opening Galleries and Service Centers and selling many Tesla S/3/X online. The lack of local Tesla Stores hasn't really impacted sales, and has actually demonstrated how little value the dealerships provide for new & used vehicle sales.
This time around, the Texas legislature is now considering a bill to prevent Tesla from operating any Service Centers in the state - which would clearly have a major impact on those of us who already own Tesla vehicles - and discourage new sales of Tesla vehicles in Texas. Service is a major revenue stream for the dealerships - and since EVs should require less long-term maintenance, it's not surprising they would now try to block Tesla from servicing vehicles in Texas.
However... If Texas does pass this bill and it is not vetoed by the Governor, this might be a good thing for Tesla in the long run. This might be enough of an overreach to build a pretty strong case that state-supported dealership requirements inhibit interstate commerce and adversely impacts customers - and could lay the groundwork for throwing out all of the dealership protections.
Though that could take years to get through the courts - and in the mean time, Tesla would be forced to jump through some extra hoops to set up a structure that would allow Tesla to provide Service Centers through (semi) independent Service Centers.
Plus, Texas generally places few restrictions on businesses, so even with the support of the dealerships, this bill may not get approved.
