Also Cybertuck turns both front and rear wheels. Rear wheels actually turn in different direction depending on speed. --- End quote --- Honda Prelude had four wheel steering 35 years ago --- End quote --- Did it do the same as what I wrote? At low speed Cybertruck rear wheels turn up to 10o in opposite direction from front wheels. At high speed they turn up to 2o in the same direction as front wheels. |

The reason should be obvious to anyone that's ever driven a vehicle. The closest to variable steering that actually works is the various 4WS systems the Japanese manufacturers used in the 1980s-1990s. Curiously they don't bother any more. --- End quote --- Strange statement and wrong. My 2005 BMW 330i (E90) had active steering and it worked perfectly, I enjoyed it. The 5-series had it even earlier. It's a standard option not only offered by BMW (I think, didn't check other brands). https://en.wikipedia.org/wiki/Active_steering --- End quote --- Steer by wire is not the same as active steering at all. Also Cybertuck turns both front and rear wheels. Rear wheels actually turn in different direction depending on speed. --- End quote --- I never said it was. Please read what I responded to. Which was: "The closest to variable steering that actually works is the various 4WS systems..." which is nonsense. Drive-by-wire is something else (and something I'd never want, but that's a different subject). |

It was also completely mechanical and didn't have 10 degrees of authority (I think it was 5 or 6), but yes it shortened the turning radius in parking lots as well as improved lane change maneuvers. My Mitsubishi 3000GT VR4 also had 4WS, but it only worked same-direction and at higher speeds. |

I found a video where it does some weird oscillation on rear wheels when changing steering direction. |

We have enough problems with people driving ridiculously oversized vehicles and killing pedestrians and cyclists in avoidable accidents. Not to mention small roads, cramped car parks... seeing someone maneuver this around a normal multistory car park would be a sight. The SUV was a cursed invention, I really wish it had never been a thing. Massive trucks like these as personal vehicles is just taking that to the next, most ridiculous level. --- End quote --- hasn't "Pedestrian Detection and Collision Mitigation Systems" with automatic braking not become mandatory yet?, I know it's been proposed so it won't be long --- End quote --- In most of Europe, yes, I believe that was part of the same package that made a reverse camera mandatory. |
