I don't know if this is well known, but Lamborghini has a track record of loud exhaust, period. Regardless of valve state. Huracan Performante owners requested that Lamborghini make the next special edition a little quieter. Reason being the Performante was too loud even on race tracks. Track day drivers know there are noise limits that vary by track. You're asked to leave immediately if you exceed the limit. You may also receive a temporary ban and/or fine.
What did Lamborghini do? Make the Huracan STO even louder across all driving modes. The company demonstrates it believes noise limits themselves are annoying. While I do like loud cars myself, sometimes a noise compliant normal or comfort mode doesn't exist.
Nothing has changed sadly.
30 was the standard up to PS3 and X360 at 720p. With the complete rework of the hardware design for PS4 and XOne, both consoles targeted 60 at 720p and encouraged developers to reach this. If the resolution is upped to 1080p, games will more often than not target 30. There are exceptions to this such as Gran Turismo. To this day, in the era of PS5 and X Series, a majority of games still target 30 because it's easier to do so and they can crank up the graphical quality.
