Even with the DK2 you can get out of your car in a driving sim you can get out and walk around your car to check it out or take in a view.
You try to make that sound impressive - (even without the following caveat statements that you failed to mention) - its not!
1) Whilst you can stand up and sit down.. positional tracking all relies on being in range of the sensor. even with the CV1, 10-12 feet away is the maximum - so you must have a small car if you can walk around it since even a Mini Metro is 11 feet in length.
2) This also requires the sensor being able to see the headset.. an object blocking its view will stop all positional tracking.
3) You are also restricted by the tethered wire that runs to the back of the headset, spin around a few times and its tangle-time.
4) There is still no body tracking.. only head tracking - you can't actually do anything whilst you are out of the car - which begs the question.. what's the fnarging point?
Like I said.. VR tech might take off in the near future.. by that point though the specs/experience are going to be wildly different.. I'm happy to wait for now.. nothing you say is going to change my mind because I've seen all I need to see.. Vive.. Oculus - they are more of a toy/gadget - in terms of gaming - I just don't find them that impressive.
And in response to the games list that you claim are all native VR games - I could only find War Thunder on the official Oculus Store... go figure!
