How Lateral Gs Work in a Car

Hiiiiii everybodyyyyy!  I ripped (“leveraged” in business speak) the below from this website.  This is a helpful explanation for how lateral Gs work in a car.  Now you know!  Explanation below:

“Lateral Gs is simply a way of expressing how much side to side grip a vehicle has. G is for “gravity” with 1.0 “g” being equal to one gravity. So a car with say .5 g lateral grip would start to slide off a corner (driven in a circle, which is how the measurements are done) when about half it’s weight is pressing outwards. So a car with a higher lateral G number has (in a steady state circle anyway) more grip than one with a lower number. Some car manufacturers deliberately don’t increase the lateral g force number of their cars to make them break away earlier, thus making them “more fun” (Mazda has done this with the Miata, and the Toyota FRS supposedly used low grip Prius tires to make it more “playful” with less “stick”, for example). There are road cars today that measure over 1.0 g, previously the provenance of race cars. Road cars driven on public streets will rarely approach this limit of adhesion…”

I also saw this photo which illustrates why roads and roller coasters utilize banked turns:

I also found the following photo.  Hold your ball joints together because this is a side splitter.  “Homojunction.”  Huh?  Huh?  You get it…
