This is similar to Bar / Barg in pressure, we are all experiencing 1 Bar or one atmosphere of pressure but a pressure gauge would show 0 Barg as it measures pressure relative to atmospheric.

If I bought a tyre pressure gauge and it read 1 Bar atmospheric I’d be sending it back as mis-calibrated.

We are experiencing 1x the force of gravity right now but if I installed a data logger into a racing car and it had a ‘Z’-axis which measured +1g stationary I would be a bit perplexed as to why it was set up that way as G is an acceleration expressed as a multiple of the force of gravity and what I’m interested in is the G-force the car is developing and not the G-force the car is developing plus 1G in case I forget gravity exists. While 1G positive on the ‘Z’-axis may be accurate as an absolute, what I would want to instrument would be relative to that.

Well right now, unless you're being surprisingly athletic, you're experiencing 1g. God knows what your theoretical F1 car is doing at 200mph to evade earth gravity.
Why are you ignoring what jsf writes?

Not in the context of a race car. G in that context is left/right accelerate/decelerate, not vertically. It's not about downforce added to earth's gravity (which, by the way, is a myth. The earth sucks). At a constant speed, the G in terms of left/right or accelerate/decelerate is zero

He’s not. Some of you are talking about convention (you don’t really discuss z axis acceleration in racing car engineering?) and TheDeuce is talking about reality. Just because you don’t measure the constant ~1G force on racing cars doesn’t mean that the car doesn’t experience it or that it’s correct to say that at constant speed in a straight a racing car is experiencing 0G. It’s sort of clear but you both mean, but it’s not specific enough to be correct.

At constant speed in a straight line a car is subjected to zero longitudinal or latitudinal g force.

I started this with the 6 tonne bombshell and it’s been interesting g to watch it unfold.
I’m going to throw in side winds and a cambered track to point out that just because an F1 car is travelling at a constant speed in a straight line doesn’t meant it’s experiencing 0G in the x and y axes.

If its experiencing any external force change (wind or change in surface profile or even Mu of the track surface) its not in a steady state or constant condition.

The only thing that matters is longitudinal and latteral rate of change (expressed as G) and yaw.
Bit in bold is not correct - if the external forces are balanced it will be in a steady state, however, external forces are definitely acting on it.

So, if we put an F1 car on a rolling road, in a lift which is falling due to gravity and happens to also be a fully functional wind tunnel - and accelerate it to full speed, whilst pressing the magic button, will Horner’s leg stop wobbling?

After 36 exciting races in a row, since we were last in France, we should get an overdue reminder of what a dull as ditchwater race feels like to watch...

When you put it like that it's even more depressing!!

Better start the rain dance, it’s the only chance! They have sprinklers there, why not switch them on and off randomly for 90 minutes?

I enjoy playing it on the Playstation more than watching it sadly... I will still watch it of course...........
