This looks pretty good IMO. I agree that VR is quite good for shorter races. I have the Valve Index still so mioght see about trying one of these quest 3s.
For races under 2 hours I could see running it. Anything longer than that I think it could be problematic. However, the level of immersion and being able to see break markers is amazing. It brings forth a new dynamic that I think needs to be considered. Super fun, but I will ALWAYS have triples too. The Quest 3 is a great entry to VR.
