Yeahhhhhh... Dammit, I'm afraid it would be in something like a WORM system... FML...
I was thinking maybe it only has the capability to keep crap for like 1000 miles or something....

At the same time, our cars don't have the same black box that the GTRs have that can inform Nissan of your launch control launches and if you've taken the car to a track

Codes and no codes (hard or soft) can be stored indefinitely until they get cleared. Today's cars can even tell in case of an accident how fast it was going, if the ABS was activated before the impact and stuff like steering input and so on. That's how investigators can tell alot from accidents when there is no witnesses,they pull the info from the vehicle.

Ok, well... I'm 90% sure out car doesn't have the black box to record all that info... And the question is how can I clear it?

The dealer can do it. Just stop by and ask to clear it. Or autozone/Advance sometimes can clear them and is free.

They have one for crash info starting production date after 8/12 but it isn't a big deal if you have one or not.
