I'm reading this argument and had discussions with people plenty of times. I then remind them of all the other companies.

Does selfdriving work? yes. Is robotaxi a real business? Yes.

Thats not the point. The point here is the valuation of Tesla because of it and thats not justifiable. Despite the fact that Tesla originally sold FSD so that everyone can leverage this feature.

So either Tesla builds a cheap Robotaxi and floods the market as a car company OR Tesla becomes a competitor on a competitive market.

Why would people adjust their lifestyles based on a Robotaxi? We have already Taxis and Ubers.

The only chance for 'people changing their lifestyles' is if a Robotaxi is always available and A LOT cheaper which then again breaks the whole valuation of Tesla.
