And as a reminder, in Texas, Tesla cannot have a dealership... it's a showroom. ;-)
You usually have to make appointments to do a test drive ahead of time as on the spot test drives sounds like a dealership thing. Texas Laws can be silly.
The guy from Ride the Lightning podcast was talking about renting a Model S/X recently. I think it was last week he gave the names of a couple of places renting them as well.
