Apologies for the energy/power mistake--you are right of course, not sure what I was thinking. I still disagree with you, though.
For the efficiency of electric motors making up for low energy density in the batteries, I beg to differ. Currently available electric vehicles struggle to top a range of 200 miles, and even optimistic claims for future vehicles are only in the 300-350 miles area. My '94 Honda Civic can easily manage, real world, 250+ miles on a small 10-gallon tank (I've repeatedly proven this with my in-car odometer). Factor in that regenerative braking will be negligible for a racing vehicle, and pit stops would require the replacement of the entire battery pack(s), I don't think we'll be seeing an electric F1 anytime soon.
Hydrogen has great energy density by mass, but terrible energy density by volume. Even liquid hydrogen packs a mere 8 megajoules per liter, whereas gasoline has between 30-35, depending on octane rating and added alcohol content. For the same amount of energy, a hydrogen car has to carry over 4 times as much fuel by volume. I just don't think a modern F1 car has room for all that hydrogen, let alone for the weight of the infrastructure needed to keep it compressed/liquid. It could be done, but it would be a very different vehicle.
If you want the best fuel, money no limit, according to wikipedia Boron seems to be the best choice. Incredible energy density by mass and volume--no idea how you'd build an engine around it though.
Um, no. If all regulations were dropped, nobody would run hydrogen fuel or electric. The power density of both mediums is pathetic compared to regular old gasoline, let alone high-tech racing fuels.
Nothing, except that this is F1, not rally. If the FIA wants Group B rally cars, then they should reinstate the Group B rally. Hell, I think that would be better than F1.
Hmm... 4wd, 2.2 v6 turbo at 10k rpm...
Is it just me, or does this sound exactly like a Group B rally car?

Or you could just make 1st gear higher.
This is LFS, we've got continuously-variable gear ratios for free. It's not the physics, it's your setup.Seriously, I'm baffled by most people's low-end gearing in LFS. If the car spins when you floor the throttle, don't decrease the throttle, adjust the gearing. You get the benefit of easier, more consistent starts, and the remainder of your gears are closer together, so you stay closer to the peak power of the engine.
Is it an optical mouse? There may be some dirt on the sensor, or it may be the surface you are using it on--my old mouse used to do this a lot on my desk, so I usually put a piece of paper or something under it and it worked fine. Wipe it off and try it on another surface, preferably something not shiny.

I find Burnout especially funny--isnt the goal of that game causing accidents? And NFS and Midnight Racer certainly reward high-risk behavior in the game as well. Anyway, ignoring what I consider to be the questionable selection of games, and the small scale of the study, it actually seems reasonably sound. 
Anyway, as another benefit besides countersteering, I also notice most "non-racers" brake in corners instead of before them, which makes me cringe. The traction circle is not an intuitive thing.

New episode just started! Now just a few hours for a rip to come out...
No, it wasn't Topgear. From one of the non-show Clakson DVDs.
If I could afford two projectors, I'd certainly go for this. But for that kind of money, I'd be tempted to just get a proper pair of VR goggles. They're getting quite good these days.

Yes it's possible to cool an intercooler with gasses other than nitrous oxide.
Though I feel obligated to point out that the cooling effects of nitrous oxide are only secondary to its real pupose, increasing the oxygen in the intake.

Don't underestimate the engine. It's only a V6, but IIRC it was originally designed for Group B rallying, and no slouch at all. The car didn't break 200 mph on aerodynamics alone.
Finally somebody gets the geometry of Chicago correct. Good job.
Although, to nitpick, I'm pretty sure that the real Chicago goes around the outside of the tire wall (the one that's actually present on the real track). But given the size constraints, your version is fine.

You know... I think I actually don't want that car. I know how TVRs handle, and I'm honest enough to say that if I had this thing, I would crash it and probably kill myself. It's a true monster, and should be handled by someone up to the task.
I'll take something sane, like a Lamborghini.

I have "sorry" on bind for the same reason I don't talk on my cell phone in the car if I can help it--it's dangerous to take your hands off the wheel. I've tried it, and I always cause accidents if I try to type in a race, unless I pull clear off the track and come to a dead stop. And then, of course, my own race is ruined.
When I use my bound "sorry" it's usually because of a mild bump or something similar. If it caused me to pass them, I'll blue flag myself and let the guy pass me--but I don't feel the need to talk about it, bumps happen in racing and I think acknowledging that something happened and then letting them pass me says all that needs to be said.
If it's a serious accident, chances are I've ended up off the track anyway, and then I will take the time to type a real message.

Interesting to see that some people already have the same ideas for corner names that I do... I was suprised to see I'm not the only one that calls the SO classic chicane the "bus stop", and Aston's "Boomerang"
was exactly what I was going to suggest, but it was already at the top of the list.

Your real car probably has a syncromesh gearbox, which helps a lot. Granted the "road" type cars in LFS should have them too.
Ask him if anyone was ever scouted for a real racing team from playing GT4. I seem to recall at least one LFS player has been.
Yah, but by then you've usually done your damage.
Re: rev limiters being standard, yes all cars have them, all modern cars anyway. They usually kick in noticeably higher than the "redline" on the tachometer, and significantly above the usual shift points, so in normal driving you never notice them.
For LFS, they are particularly needed for Rallyx. Speaking from pre-rev limiter LFS experience, going over jumps would regularly popcorn the engine. Several of the jumps on the BL rallyx track can be taken flat out, but the sudden loss of load on the driven wheels would lead to a sudden spike in revs, and without a rev limiter it was very easy to cause damage. Adding the rev limiter (and also I believe decreasing the acceleration rate for unloaded wheels) fixed this problem.
The FXR is also best launched while bouncing off the rev limiter, but that's actually due to an issue with the way the turbocharger responds to throttle input.
I still think you're nuts about TC being less assistance than rev limiters. I think you're seriously underestimating how much TC aids the control of the car--it's like anti-lock brakes, but for the gas pedal.
New raceabout
I just stopped by the website for the real Raceabout (http://www.raceabout.fi/) and I noticed that LFS is using the 2002 model, when a new version has come out. The styling has changed a little (I think the old one looked better), but more importantly it's got a more powerful engine now (+17 Kw, +60 Nm), and apparently a redesigned rear suspension. It weighs 5 Kg less, too.
So Scavier, where's my new RAC?

I agree with you there, in principle. The problem is that, personally, I get as much enjoyment out of tweaking setups as I do from the racing itself. You've heard me discussing gear ratios in your GRC threads--for me, getting the "perfect" set of ratios is as satisfying as winning a race, even when I know perfectly well that it doesn't make any difference on the track. I actually use the skidpad to test grip, I've had the AI run hundred-lap races by itself so I could monitor tire wear, and I lie awake nights trying to figure out the effects different LSD settings have on handling (they still confuse me).
Yes, I'm crazy. But the point of LFS is to have fun, and I'm having fun. Suspension Damage I can do without, but don't take away my tire monitors and force view! At the very least, you should be able to see tire wear and temperatures when in the pits--it's the only way you can tune camber settings, and it can be determined on any car just by looking at the tires and poking them with a cheap digital thermometer.
So a rev limiter, a standard feature of all automobiles which provides no benefits to speed or control, consisting of a simple fuel cut-off switch triggered by high RPMs, is "nanny business"...
But traction control, a complex computerized system which allows the driver to ignore all aspects of fine throttle control during launches and corner exits and simply floor the gas, is okay?
illepall That better be sarcasm.Fair enough. I confess pretty much all my materials experience is from battlebots, where aluminum and titanium are the rule (along with high-strength plastics and carbon fiber/kevlar composites, and a smattering of magnesium). Steel is relatively rare--usually just S4 tool steel, which you obviously wouldn't make exhausts out of.
So I don't know much about it. Funny, really--I know a lot about the "exotic" materials, and very little about basic steel.
Yah. There's a number of reasons why. First, you save a little time because you don't have to move your feet to get from the gas to the brake pedal. Rally drivers use it a lot because they spend so much time quickly jumping betwen braking and accelerating, in track racing this is less critical. Second, you can press both gas and brake at the same time, which can be advantageous in certain circumstances, especially in FWD cars..
What's fun is watching someone who uses both heel-and-toe and LFB. Someone once said, "It's like he's playing DDR down there"
