If a NASCAR can do a lap around 90mph then it will be no problem for a F1 car to do 120mph.

I am most certain that it was JJ, the current driver of the 48 Lowes Monte
Carlo (I got his sponsor plug in for him LOL! and I ain't even a real fan of
his...) I will stand corrected if someone can point out factual data that
said it wasn't, but would also put up this month's mortgage that it was him.

Just fyi, I've heard John Fitch preach, "pave the gravel traps", for
several years now, although his first public press releases are from 2
years ago.  Here is a recent press release that might be of interest:

There is a lot of interesting safety related material on John's site:

Yep.

WC cars are far more capable of tire 'tuck-in' than an Indy, Cart or F1 car.
Hell, I don't even think it's _possible_ on one of those cars unless
something mechanical breaks.

Exactly. As Emeril says, "it aint rocket science". The same technology used
for highway light poles could be easily converted to the armco barrier to
make it ideal for quick replacement.
 Even further, by controlling the shear force required, you could even make
a double armco barrier to absorb the impact in stages.

F1 would most likely use the full "sports car" course.....an Audi R8 turns
lap times on that track of about 1:23.  I'm not exactly sure how long it
is....but its about 2.5 miles with it....give or take a scrinch!

know they would be well under that with the current

Tim...

Agree that the main grandstand offers the least (all over view) view of the
entire course....but that view of the cars coming down through the esses
nearly straight at you is pretty cool.  And, having the pit action directly
at your feet......that's worth giving up a few sections of track view.
Don't you think?  So, in the terrace seating....you gain "view" but loose
the pit action.  Kind of a good trade I think.

I would guess that F1 would use the carousel turn....the full "sports car"
course.

Well....in the full "sports car" track.....there's as much overtaking
possibilities as any track I've driven in F1-2001.....so I'd have to
disagree with your assessment on a lack of passing zones.

Eldred....I don't remember the exact years....but CART did run at Sears.
Seems like it was for only like 3 years, though.  But I could be wrong.  It
was back when Mario was younger....maybe late 70's early 80's maybe?  There
should be something on the CART website about historical races....or such?

Dang it, Doug.  Wished I'd known about Fitch 2 years ago.....I could have
used that stuff to stop the Sears people from laughing at me......about
paving the sand traps.  They don't laugh now....but they sure got bellies
full of it two years ago (at my expense)!  ....lol...

   Can you explain the mechanism by which that occurs?

   I can imagine that it sure as heck *feels* like you are
accelerating when you suddenly lose all braking capability (and much
directional control) going from pavement to wet grass, but do the cars
actually increase in velocity?

"But in a way, fear is a big part of racing, because if there was
nothing to be frightened of, and no limit, any fool could get into
a motor car and racing would not exist as a sport." -- Jim Clark

Well, the car wouldn't accelerate in the grass unless the car was
heading downhill. Maybe that's what Tom means.
