They are cornering rideshare and automatic vehicles. They are the sole provider of an automatic vehicle.

Fair enough, I suppose they have a monopoly. Good thing that isn't illegal if they're not anti-competitive about it.

They aren't the only autonomous vehicle for hire service. Zoox is operating in Vegas.

Even if they were the only one, it would be odd to classify autonomous rideshare as a distinct market given they compete directly with other vehicle for hire services where they have nothing close to monopoly-like power.
