I've got a question, in f1-02.car I can read this :

Code:
```[fuel-tank] position = -0.00, -0.30, -0.30 capacity = 180 volume = 76 fuel-density = 0.8```

What are the units used here ?

For example AX2 has :

Code:
```[fuel-tank] position = -0.17, -0.26, -0.56 capacity = 0.0492 volume = 0.0492 fuel-density = 730.0```

This is not at all the same units, but they're all version 2 of car file.

I looked at the weight of F1, without fuel (I don't know how to calculate his weight) its mass is 531 kg, far from 673 kg in the comments.

Another things, sometimes at 1st speed (and only at first speed), throttle is getting crazy, if I push my pedal too quickly and release it, throttle stays at fool. Someone saw that too ?

Fuel density only matters for fuel tank weight(in kg) = volume * density. Fuel is consumed per volume unit. See fuel-consumption value of the engine.

Confirmed.

So I calculate that F1-02 is 591.8 kg at start, that's illegal.
We must make it heavier, but where ?

I forgot the wheels. Wheel mass/inertia are optional parameters, are calculated from tire dimensions if omitted. To see the weight of the car and some other parameters try "vdrift -debug".

To change the weight and weight distribution modify the mass particles.

I think I've fixed the bug. Can you test r2867, thanks.

Another prob: F1-02 has actual the same tyres front/rear.
ItÂ´s not really driveable.

hmm.. i need to come back soon. i still need to add stuff to rouen...

'n stuff, man. yeah.

oh, when we add back the red glow to the back of cars it should be optional in the .car file. that way i don't have to go through every .car config guessing where to situate lights before the next release. is that doable?

I think NaN has been planning to redo the .car files, and one of the changes I saw him mention was making the placement of lights more general so a car can have zero brake lights or several.

I've added optional brake lights support to car config (XS.car). Would be great if someone could test it, don't have access to my main rig atm.

doesn't appear to be working. no compile or running errors, either
