I think I’m confused on your point.
I interpreted your statement to mean “adding a requirement for certain types of characters will decrease the number of possible passwords compared to no requirements at all”, which is false. Even in your example above, with only two letters, no numbers / special characters allowed, requiring a capital letter decreases the possibilities back to the original 676 possible passwords - not less.
Perhaps you’re trying to say that passwords should all require certain complexity, but without broadcasting the password requirements publicly? I suppose that’s a valid point, but I don’t think the tradeoff of time required to make that secure is worth the literal .000001% (I think I did the math right) improvement in security.
For sim, I utilize iRacing to practice and learn tracks before real life amateur endurance races in champcar and lemons as well as track days.
IMO iRacing physics are so good and the tracks are so well modeled that it’s a very effective learning tool. It’s the first sim since Live For Speed that really feels close enough to real life for me to forget I’m playing a sim.
Plus traffic management and race craft are so crucially important in wheel to wheel racing & I simply don’t get any other opportunity to practice those.
