Is that because it is bad, or just because it is different, and not played with long enough to understand?
As a driver, what is the benefits of 4WS? And what do you lose? Is it more viable in a vehicle with 4 wheel independent drive? Could it be implemented mechanically without computer control?
BTW: I have never driven a 4WS forklift, but I have operated several rear wheel steering models. Even the high reach trucks don't have 4WS. In my mind, I can see it as advantageous because the traction of your tyres is evenly split between turning and accel/brake. If it is possible to decrease the front wheel vector by having a rear wheel vector, you could have a T/P split of 70/30 + 5/95 (4WD/4WS) instead of a 90/10 + 0/100 (RWD/FWS). Thus the 4WS/D setup would have more available traction for accel/braking.
If my understanding is incorrect, will someone please inform me of how it really works!
