Hybrid implementation (Regen and boost) is incorrect and bugged in several ways

Yes indeed, there remain many issues with it.  Not the least is control of boost level past the 70%, the gutted engines below 70% throttle (so you can delay deployment)

the amount of brake pressure required to even start regen in the game, and so on.  The points are on the first page.

This should be fixed/implemented to just work as close to the real thing as possible, It's not really some massive and super expensive challenge, and there should be some authenticity to the driving.
