That ship sailed a while ago.
Home Depot is open and packed to the gills (literally people lining up to get in the front door at my neighborhood Home Depot which is about 20 minutes from the Tesla factory). Most of the people shopping there aren't doing anything essential -- their home improvement projects and gardens can wait.
Similarly, marijuana dispensaries are still open in California. They aren't really essential: unlike in the case of alcohol, withdrawal from marijuana is not dangerous and smokers could go without it. Yet dispensaries are "essential".
On the other hand, car parades and just "going for a drive" are officially discouraged even though there is no chance of contact with strangers when you are inside your car.
At this point, to say that those businesses are essential, and yet a car factory is not, is plainly ridiculous.
What kind of rational decision-making process results in marijuana dispensaries being more essential than car factories?
The government can't get out of this by claiming it can't pick and choose, because it has already been picking and choosing for a while. It has given the green light to more questionable cases than the Tesla factory.
