Well, I've gone through the process of requesting a vegan steering wheel and had no luck.
After configuring, I called a few times to request it and was always told that this was something I needed to work out with my Internal Delivery Advisor (IDA) once one was assigned.
I was assigned an IDA last week, requested the vegan wheel, and the response that came back a couple days later was this:
"Our seats are made out of Premium Engineered Material (polyurethane), and the steering wheel is leather. We don’t have the ability to switch out the steering wheel with a vegan option, I have confirmed the information with my supervisor."
I politely pressed the issue, and repeatedly pointed out that Franz and Elon made public statements at the shareholders' meeting that an off-menu vegan offering was currently available for those who request it. I asked to have the supervisor check with management about the public statement. The IDA checked again with a supervisor and replied that while they are working on a vegan option (with specifically no timeframe), nothing is available at this time.
She also informed me that my car is available for delivery next week! Just need to decide now whether to take it or hold out for a possible vegan offering in the coming months. I'm sure there's somebody here that wouldn't mind at all if I deferred!
