When physics goes along with sim racing
Tekijältä Nauval Setyawan
I've seen some drivers doing a 0.2-second gap between a car in front of them, down a straight, and think that it is perfectly fine to continue to stop at their normal braking point they used the lap before...


In short: IT'S NOT!


Why?
Have a read :)

I've seen some drivers doing a 0.2-second gap between a car in front of them, down a straight, and think that it is perfectly fine to continue to stop at their normal braking point they used the lap before...


In short: IT'S NOT!


Why?


Because doing a 0.2-second gap from the car in front down a straight, lets say Blanchimont, Spa at \~255km/h, both cars are travelling around 70 meters per second.


That 0.2s gap at 70 meters per second is a 14-meter gap nose to nose from the cars


14-meter = 3 car lengths (average car length in-game is about **4.7-meter**)


*(kmh x 5) / 18 = speed in meters per second*
*(255 x 5) / 18 = 70.8 m/s*


*m/s x gap in seconds = gap in meter*
*70.8 x 0.2 = 14.16 meters*


So, If you were to brake at 0.2-second gap on your normal braking point into a tight corner such as a bus stop chicken (chicane) or a hairpin down to \~80 Km/h.


At that \~80Km/h, both cars will slow to \~22.2 m/s... Your distance from nose to nose will now be about **4.44 meters**... (a number less than that average car length mentioned earlier)


If you were driving behind a guy in a Bentley with his **5-meter** car length... your nose will now be **22 inches deep** in Mr Bentley's backside! (*That's 56cm!*)


Mr Bentley surely will not appreciate you penetrating him like that, and taking a sniff... As both of you's will now spill your SA everywhere due to those **22** inches of action!


This wouldn't happen if you backed off just before braking to a much safer \~0.3s gap (*6.6m nose to nose, with 1.6m social distancing between the cars at braking*)
or even better is to brake earlier, and then modulate the brakes to keep close to him after the braking zone, and into the turn in.


**Brake modulation** = Brake early, then let off very slightly to come closer to the car in front again, and brake again to slow the car down to appropriate speed for the corner.
Notes
* \- Don't penetrate, tap or grind people unless they consent to it.

* \- If you're unsure about the gap and/or car distances at certain speeds, back off.

* \- If you do know the gap, always brake earlier in situations when you're close to the car ahead.

It’s much better to focus on the corner exit and get alongside your competitor before the next corner
Only ever brake normally (in this case 'later') if you are side by side and your car has an overlap, and you are on the correct side of the track.


braking late isn't the optimal way to overtake, there are some situation where you might find this, especially when you are side by side with someone. Although braking late can get you ahead, you need to know what the limit of your car is.


Because *"Braking late"* = you doing an EXTREME-ULTRA-SUPER-LATE-BRAKING! and going off into a ditch in front of some old grandmas house or The Lord of No Consent: Return of the Penetration.


Brake Early... Coast... Turn In... Accelerate...

one tip i wish i had learnt earlier, is that when chasing someone into a corner lift off the gas 20-50 meters before your braking mark, and instead focus on getting a better exit. this is especially useful in a game like acc where the skill gap in a lobby can be massive, and therefore difficult to know where someone will brake unless you have been following them for a lap or two.

oh yeah, and instead of blaming whoever you made contact with, look back at the replay and analyze the incident. Even if you weren't at fault, look at what *YOU* could have done differently. Same goes for if you were at fault, of course.

ALWAYS GET CONSENT.

This also does not account for aero loss being that close, which in turn impacts braking and car handling at speed.

I myself have been guilty of getting overly close, but often braking a bit sooner than the car in front can allow better handling through the corner.

This also does not take into account what happens when the car in front loops it and you are too close to them. So yeah some extra space can make the difference, be it from handling through the corner or not being inside the other car you are following.

have you even played online? all these sim setup wanna be's see your car on racing line? no matter dive bomb even at turn 1 monza where its a single car gap unless you do formation lap speeds ... they toss it up the inside like max verstrap-on and shag your ass into the shadow realm... the problem with sim racing is not physics based braking points its the fact that EVERY SIM RACING CUNT thinks their shcumi or hamilton and actually know how to drive , when in reality they can drive to save their lives , id say 90% of sim racers cant complete a clean LAP let alone a clean RACE .. that and the fact sim games have no damage usually and if they do its not harsh enough .. got race destroying damage? cuz you drive like a bitch ? nooooo problem just reset to pitlane get magic repairs wait 1 minute for game to be done slapping ur wrist like a ninny and then proceed to do the same shit again ...

If not gap don't go.

Car not in way, Brake normal.

Car in way, Brake not normal. (:
