And in that context, only our 6MT Sedan has a hand-brake. But even that's not true, because what we actually have is a lame-azz parking brake, not a proper emergency brake. I can't tell you how many times I've approached a parked police car and instinctively yanked on the brake handle, only to be foolishly reminded that nothing is going to happen.
Lol I have told my gf and other friends about this trick for years, its just so obvious otherwise..

As for the VDC, unless I'm launching, its always on. I love to spirit some of the Ozark mountain back roads and you can feel right about when the tires let go the slip will compensate and still allow me to throttle through. Our VDC has come a long ways since the early G's.

It also begs the question as to why Nissan made the decision that with VDC off, it would still use the brakes to stop slip in a car with a limited slip differential?
The only way to truly turn it off is to wire in a YAW control switch in the center console.

Our limited slip diff uses a "viscous coupling" which gives about 20% "locking" effect. That is not very much and it would be possible to get stuck with one wheel spinning. By using the rear brakes, it can transfer much more torque to the wheel with the most grip.

Why does Nissan do this with VDC off?
Sometimes the only way to get out of deep snow/mud/gravel, is to allow some wheel spin and the system sends the torque to the wheel with grip.

What is different from VDC off to wiring in a YAW switch?

With the VDC turned off, the ABLS is still on as shown here:



ABLS will activate the brake on the wheel with the most slip to reduce oversteer. The YAW sensor is how part of the system that detects the oversteer situation so if you disable the YAW sensor, then ABLS is disabled.

I find the ABLS extremely annoying. I simply unplug the YAW sensor which disables the ABLS and also traction control. ABS still works normally too. The only downside is the light that is flashing in the video stays on all of the time.

Without ALBS inside tire will spin when powering out of a turn. ALBS helps to put more power down by braking the inside wheel to transfer more torque to the wheel with more grip (outside wheel).

ALBS greatly increases the chance of oversteer when accelerating out of a turn, which we want.

Removing the YAW sensor does not disable ALBS as it uses the ABS module to function (wheel speed), it just stops you from seeing the flashing light.
