Darting.

This has a name. It's called tramlining. Low profile tires are more prone to it, but the G37 does not have especially low profile tires. Some models of tires are much more susceptible. The predecessor to the Bridgestone RE050's which come on the S model, the RE040, was notoriously bad. I had them on my BMW 330 and it had a mind of its own. I do not notice it at all with the 050's on the S.

wide grippy tires = channeling...or tramlining as said above^^
I had this on my IS 250 and experienced it on a Porsche that I test drove...
I really think it's just a function of the reeeealllly wide tires finding themselves or centering in the channels on the highway....
I think making sure they stay inflated to exact right PSI helps keep this to a minimum.
Some companies overcompensate the steering feel to very tight to "fix" this...but that leads to very heavy steering...another bad feature of my former IS250

Arm flailing tube man
well it sucks sometimes, but at least I know it's nothing wrong with my particular car. luckily, there isn't a lot of those kinds of roads in my area.

i do not think i experience this. probably because i havent notice it yet. how bad is it. you are driving on the highway then all of a sudden the car just move without you doing anything to it?

The darting behavior stems from the second gen FM platform, at least the way the Factory has it set up. It is more noticeable as you go to lower profile tires. I haven't had any chance to play with alignment settings yet, and it may take me awhile to have the chance. But, I do notice an improvement by running one more pound of air pressure in my front tires than the rear (even though the Factory says use the same pressure front and rear).

10 and 2 is the only way I drive with my hands on the wheel at high speeds... Actually 9 and 3 so that I can change the stations and stuff... Keeps me in control and going in the direction I want to...
