Edit: never mind, not worth the whining. It's just massively disappointing that such a good driving game is let down by the community and the devs enable it or don't do enough to discourage it.
This may sound condescending as I haven't seen your races, but if I were getting bombed enough times that my SR is 'stuck', I'd start checking my braking points and lines.
The way SR punctuation works for a race makes it that roughly you can have one heavy incident, that is a crash that sends you to a trip off-track, and still end 'blue' or positive punctuation. SR's goal is not to bracket users, its end point is
everyone reaching 99 points. So the sum of clean sectors for any given race, plus the extras for clean overtakes and likely some other mysterious conditions gives enough room. That's why you'll see a handful of DR S - SR S "dirty drivers", they know some "tactical tackles" or "calculated brake checks" won't affect his end result as long as he doesn't do that multiples times in a race.
I know though that a crash at the start of your race can completely throw you off and then you rack up little mistakes overdriving, trying to make up for the time lost.
On this topic as a whole, rules and "punishments" are extremely complicated because
the majority's intent is indeed to race fair and clean, so the immediate reaction to any penalty is "This is not fair, I was driving properly!". From there on, it's a parent's discipline dilemma.
I'd say even through the major changes the game's ruling system has gone through, it does a good job at that.
What is poor or almost non-existent is its safety education.
