That's pretty sick. I've never played iRacing before but I've watched a ton of it being played and the driving seems fantastic. A more widely available Nascar game with that more realistic, tight, simulated driving I can see being really fun. I tried some of the Nascar Heat games and whilst fun I felt they never really took it to the next level and it could have really benefitted from a lot of quality of life improvements.
'Everything you've been asking for' gets me excited to see what this looks and plays like.
