On a reasonably well constructed car, loss of power steering at highway speeds is barely noticeable. Loss of power brakes is a different story. An inability to actually get all the way off the highway before running out of speed could also be quite dangerous, and a loss of power steering can indeed make it quite difficult to maneuver at low speeds.

- Eddy_Viscosity2 1y agoIf its drive-by-wire steering, then isn't loss of power steering the same as loss of all steering?
- mikestew 1y agoIf its drive-by-wire steering… Which it isn’t. What production passenger vehicles have no steering column? (EDIT: oh, yeah, forgot about Cybertruck.)
- theluketaylor 1y agoThere are many passenger vehicles with brake-by-wire, but only one I'm aware of with steer-by-wire: cybertruck
- lsaferite 1y agoCybertruck for one. I searched and found several, some without any manual backup. That's crazy to me.
- inamberclad 1y agoThe cyber truck, tragically.
- qwerpy 1y agoI’ve really enjoyed it on mine. Steer by wire enables progressive steering. Having to turn the wheel over and over in other cars to maneuver in parking lots seems laughably primitive now in comparison.

- qwerpy 1y ago:P
- constantcrying 1y agoE.g. the cybertruck. It will also be more common as vehicles become more automated.

- lsaferite 1y agoI'm shocked (literally) to see there are production vehicles with steer-by-wire. Couple that with OTA updates and you have a vehicle I'd refuse to ride in, much less purchase.
- 20after4 1y agoI think most recently developed large commercial passenger aircraft are completely fly by wire with most controls lacking any physically interlinked backup. Thinking of this somehow reminded me of the most harrowing aircraft disaster that I've ever read about: https://en.wikipedia.org/wiki/United_Airlines_Flight_232 https://en.wikipedia.org/wiki/United_Airlines_Flight_232 It's both tragic because half of the passengers were killed but also miraculous that anyone survived at all.
- jmount 1y agoHopefully I am not too naive, but I think aircraft safety redundancy remains above retail car standards. Also, in aircraft they "have time to solve some problems", versus freeway bumper cars.
- 20after4 1y agoIndeed, but read the link I posted above if you're interested in a fascinating case of failed redundancy.

- raverbashing 1y agoYeah Also people say "oh what if fly-by-wire fails" well what if traditional hydraulic controls fail, which has happened plenty in the history of commercial aviation Everything can and will fail at some point No redundancy is redundancy enough in some %0.xx of cases. You can always reduce the number, but never make it 0
- OptionOfT 1y agoI think there are only a couple of cars that are steer-by-wire. The Infinity Q50, QX50, QX55 and QX60 (with backup that connects upon electric failure). Without backup, but triple redundancy, can be found in the Tesla Cybertruck. But I'd take that redundancy with a grain of salt as they don't have the best track record telling you the truth. That said, I really with companies would go back to the good old hydraulic steering. I don't need self-parking. But self-parking needs at least electric steering (with our without steering column).
- ajross 1y ago> self-parking needs at least electric steering You can control a hydraulic system automatically. That's literally what ABS braking is on the same cars already.
- dismalaf 1y agoWhich vehicles other than the Cybertruck have drive by wire steering? To my knowledge it's the only one without a physical steering column...
- pavel_lishin 1y agoI've lost power steering on my dad's F250 once. It was incredibly noticeable, since I had to crank the wheel like a ship from the age of sail in order to get onto the shoulder. I guess you could argue that it wasn't a reasonably well constructed car.
- slau 1y agoIn most situations a rudder is very, very gentle on the hands. You rarely have to crank down hard.
- collingreen 1y agoI think the comment was about how noticeably _far_ they needed to turn the wheel not how hard it was to turn it.
- amluto 1y agoThe amount you turn the wheel is identical [0] with or without power steering, unless perhaps you have one of the weird variable turn ratio systems. In a conventional power steering system, the steering wheel is linked to the wheels, and the power steering applies torque to help you turn the wheel but does not change the relationship between the steering wheel and the wheels. [0] Almost identical. The steering has some flex, and the amount it flexes is related to how much torque you apply. But this is a tiny effect.
- pavel_lishin 1y agoMy comment was explicitly about how physically difficult it was to turn the wheel. I had to crank it over far as well, in order to get off the highway.
- dzhiurgis 1y agoDid you mean tiller? These are hardly found on larger ships. I still like them for how much better you feel sail balance.
- NewJazz 1y agoLoss of power steering is definitely noticeable. Especially when it comes to getting off the freeway.
- rpdillon 1y agoLost power steering at highway speeds in my '91 Corolla a couple of decades back. Didn't notice on the highway (belt just made a loud pang and I thought "What the heck was that?"), but as soon as I took an exit and had to turn at the light, I seriously had to muscle the wheel over. Good learning experience about what power steering offers.
- EvanAnderson 1y agoLosing power steering would be no big deal. Anything that caused a sudden loss in forward velocity worries me. There's construction on the Interstate highway in my area with lanes that have no "breakdown" space ("contraflow" lanes). I would be terrified to lose power in that lane. I would be worried about getting rear-ended and / or causing a pile-up.
