The feature is too complex to be ready in time for launch.
The vehicles’ quad-motor motor configuration is what makes the function possible.
Rivian’s been the subject of countless news stories over the last few years. From the vehicles themselves to the numerous backers willing to inject billions into the start-up, Rivian’s made nearly as many headlines as Tesla. One topic was the brand’s ultra-cool “tank-turn” feature but unfortunately, it’s not quite ready for production models.
What makes the Rivian R1T’s and R1S’ tank turn possible is that both vehicles have individual wheel motors. Because of this configuration, the wheels can turn in different directions thus enabling them to rotate on the spot.
Apparently, according to Teslarati, making the function work right and safely is extremely complex. For example, though the tires are on similar surfaces, not all have the same amount of grip. This means that some wheels require more or less power to initiate the turn. Once turning, the vehicle could spin in one direction instead of in place because of wheel speeds, surface changes, and so on.

Rivian engineers are still working on the feature to make it as safe as possible. There’s no word as to when the tank turn will become available. For the moment, all of Rivian is heavily focused on successfully launching the R1T and R1S.
