Also, it's the Roadster -- a $100k+ supercar which sold less than 2500 units. Not the sort of thing an owner would typically be doing DIY repairs on, if they're even driving it. (I wouldn't be surprised if a substantial number of the remaining Roadsters are held by collectors.)
Yes it's a stunt, but c'mon, those "special tools" are something every manufacturer has, and they're usually not that special, and they're easily replaced.
One of the Tesla ones is literally a storage cart. Another is a sawed-off 26mm wrench head, the "clip tool" looks like it could be cut out of plywood or a sheet of metal in a few minutes.
