This was one of my major complaints about n1. A light tap to the AI
would almost always bring out a caution. I'm pretty sure that papy new
there was a problem with that and addressed it in N2. In real NASCAR
racing, competitors can spin out or crash without a yellow flag, as long
as there is no debris on the track, and the cars involved get moving
again. So this is a fair representation of the real thing that we find
in N2. It isn't perfect, but it works out well, i think.

How accurate a representation of 'true' Nascar racing is the use of
yellow flags in Nascar 1 and 2 ?

In N1, I found that I only had to so much as 'nudge' another car and
the yellow would come out. However, I have recently installed N2, and
have seen cars spin out and take other cars with them, _without_ a
yellow flag appearing (btw, i have got yellow flags switched on )!

Which is more accurate ? I haven't seen many Nascar races (the sport
hasn't exactly got a high profile here in the UK), but I feel that the
reality must lie somewhere between these two extremes.

Also,why is there such an obvious difference between N1 and N2 ?

On a funny side note.. I hear the spotter say wreck in turn 3. I get
there and I have to drive over fenders, bumpers, tires bouncing around
and who knows what else, but no car around and no yellow flag. What do
they classify as debris? A whole engine lying on the track?

One reason the N2 yellows are better represented is that Winston Cup
driver Bobby Labonte helped with N2.

You have experiences the phantom crash.

You were the dialer in a multiplayer race.

Happens alot on the parade lap. Or you were racing and you just got
passed.

The communication between systems doesn't include all of the other cars.
It's just a subset, about 5 in front and 5 behind you. If you get
passed, the car that was 5 in front of you is now 6 in front of you and
therefore doesn't get sent to you any more (until it becomes one of the
10)

The program doesn't immediatly determine that the car isn't supposed to
be in the packet and thinks it's just late coming in.
This is where the prediction code kicks in. It appears to let the car
continue in it's previous direction. In a corner this means towards the
wall. The program will give up on the car after a few packets so MOST
of the time the car just disappeares. Sometimes however the car hits
the wall before it disappears. Thus the depris. The car itself will
disappear before you get to it's location so you will never SEE the
car.

The accident is just in the view of the client, because it has
inaccurate information. The host however knows exactly where ALL of the
AI is at ALL times to it applies damage to the car only when it deems it
proper. The Host doesn't know the true location and status of the
client's car until that information is sent to the host. The host
accepts the data and goes about its calculations.

Due to latency, and related bandwidth there are limits to how "perfect"
the multi-player racing can be via modem.
