And again - no. I am telling you they are not 'using' the system, they are exploiting it.
Big difference.
I understand you believe in moral relativism, but I don't - exploiting is cheating.
It's a competitive game. As long as what they're doing is within the rules, and it is, then it's fair game. We're not talking about your made up "it's only fair" rules. We're talking about actual enforced game rules.
You can not like it, but it's not cheating. The system is working exactly as intended. It's not like they're avoiding punishment, they're getting and serving the penalties. They've simply figured out that it's better to do that than not get any penalties at all. That's called playing well.
Welcome to competitive gaming. If there's a winning strategy within the rules, then people will use it. If you don't like it then you can use it yourself, figure out a counter strategy, or just wait until a patch changes the rules (if it ever does). But for now, these are the rules.
You can’t avoid someone plowing into you from behind at full speed. There’s literally no way to avoid that.
Uh huh. I have something to show you.
Watch into the first corner. The next lap too, if I recall correctly. He manages to dodge dive bombs twice in one race. It's harder off the start because there's so much going on, and sometimes it's impossible to see because they're blocked by other cars. But it is not impossible, it's merely difficult. Add in that a rammer is likely to be traversing a certain part of the racetrack (usually the inside) and try and avoid that, and you can give yourself a very respectable chance of making it through.
Defensive driving is totally a thing.
I don't think this is true. What a no-fault system teaches you is how to drive without really racing like you want to, long enough so you can finally be paired up with the less rambunctious racers.
That's kind of what real life racing is like, though. You don't get to go out and just race however you want with no thought for the cars around you. You have to consider that if there's an incident, even if it's not your fault, you risk damage to your car (that you'll have to pay to have repaired) and damage or death to yourself.
Hence, real life drivers generally pay each other a certain amount of respect.
The only racing system that lets you race however you want is full time ghosting. The whole point of racecraft is to allow you to cleanly deny the opponent the optimal racing line. SR systems introduce consequences for all parties in an incident, not just whoever happens to be unlucky enough to end up in the weeds. It creates a system more like real life, where everyone has incentive to avoid incidents because they don't want to end up with a suspension strut through the eye.
