Rockstar animator's demo reel seemingly reveals GTA 6 gameplay animations

It has been claimed that unreleased Grand Theft Auto 6 animations have surfaced online after being included in a Rockstar animator's demo reel on Vimeo.

The details:

• As spotted by Reddit user throwaway-sadkid8012, the now-removed demo reel from Rockstar animator Benjamin Chue, found on Vimeo, included several clips from the development of Red Dead Redemption 2, Max Payne 3, and Grand Theft Auto 5. However, it is believed that the first two clips are directly from GTA 6, as neither has been seen before.
• The first clip features an unknown male character removing and getting on a rental bike before returning it and dismounting. The bike, referred to as a "LomBike" on its model, suggests rental bikes will be available in GTA 6, as the name is seemingly a play on words of the real-world rental "Lime" bikes and the fictional "Lombank" previously seen in GTA 4 and 5.
• The second batch of animations in the reel shows a female character, who is likely protagonist Lucia, hopping off a pickup truck in multiple ways, including one animation where she swings from the truck bed to the ground and another where she jumps from the truck roof.
