Re: IndyCar Series

conflation danger ! - different factors (blood oxygen and inner ear effects) being jumbled

(a) 5.5 g laterally ie what F1 has approached briefly
(b) 5.5 g driver-vertically sustained ie what aviation does
(c) some 5.5 g vector combination of lateral and vertical

the inner ear is not a balance cell (like an absolute encoder)
it resets its frame of reference every 5 seconds (like an incremental encoder)
ie after 5 seconds your perception of an out-of-balance state will replace itself with a perception of an in-balance state
but training can fix this

Re: IndyCar Series

Does anyone know the front overhang length of the current Indycars is?

Similar to F1, ~1.2m. Using the Indycar rulebook requires a bit of maths and some guestimates.

The car is 201.7" (5123mm) long and the wheelbase is between 117.5-121.5" (2984-3086mm), so front and rear overhangs combined are 80.2-84.2" (2037-2139mm). The TE of the rear wing mainplane (RWMP) is 161.96-162.06" (4114-4116mm) behind the "O-line" which I assume is the front of the chassis? The "O-line" to the TE of the FWMP is 13.675-13.775" (347.3-349.9mm) so that would seem to checkout using the pic below, and would mean the nose cone is ~750mm long - which it is. Eyeing it, the trailing edge of the RWEP are ~800mm behind the rear axle line, so the front overhang must be ~1.2m. The tip of the nose isn't quite 2x the nosebox length from the front axle line, so that also seems to confirm ~1.2m!!

Re: IndyCar Series

Good effort Will Power, for being the 1st Aussie driver to crack an Indy 500 win.. at long last..
& on the same day as his F1 compatriot, Dan Ricciardo - finally scored his 1st Monaco G.P. - win..

But sadly.. no milk 'shoey' - on the podium - from W.P., though..

I just read the driver was the VP of GM??? Isn't the safety car driver a (ex)professional??? Or is it just for the warmup laps???

Usually it is, Oriol Servia was on hand (and drove the backup car), i guess nobody wanted to tell the guy responsible for making half the engines on the grid off

If he was not a proffesional driver they deserve that ridiculous

From the motorsport article:
Reuss, the executive VP of global product development, lost control under power and over the crest on the exit of Turn 2 of the Belle Isle track.
I guess it doesn't mean he's not a racing driver as well... but according to wikepedia he is not - however there's a quote from him that he's done it many times before.

Maybe I'm a bit F1/Euro -centric but it feels preposterous to let an amateur anywhere near a live race track.

"He's done it many times before..."?

Whaaa... stuck the 'vette - nose 1st - into the wall?

What's his 'catch phrase' for when he does this 'party trick'?
