94 J30T HICAS four wheel steering

[Victor]

The owners manual says the four wheel steering only is activated above a certain speed, and either turns the back wheels in the same direction as the front, or in opposite direction than the front, depending on speed. I had someone follow me and they said they couldn't observe the back wheels on my car turning. Is that because they weren't turning, or is the amount of turning so small that you can't notice it from a distance?BTW, it seems to me four wheel steering would be most useful at very low speeds like when parallel parking, so why they only made it active at higher speeds seems like a bad design decision to me.

Yes, the amount of steering is very small and difficult to notice...around a degree or so. Honda had a 4 wheel steering system used for low-speed situations like you mention, and the degree of steering was more noticable.

HICAS has a different purpose. Since small changes in toe can make a noticable difference in vehicle dynamics, HICAS is used to help fine-tune vehicle balance on turn-in. Here's an illustration by Nissan (for the 240sx specifically, but the system works the same on all cars)"

I love HICAS, zero body roll, very flat cornering-like your on rails, I can take a lot of corners at a higher then posted speed limit without losing control.
