A 1980’s era Honda Prelude had rear steering, IIRC.

you cant even go from Drive to Reverse without swiping on the touch screen. will that work with thick gloves on in the winter time? really user friendly...
Yes, we had one. It made parking much easier, but was disconcerting at first. And it was all mechanical, not electric.

I wouldn't say that but only Tesla has a (presumably) FULL 48v system in place of 12v. Plenty of manufacturers have produced 48v systems for certain things, but none of them have replaced the entire 12v system with it. For example Porsche has used a 48v system for their active body control since 2019, only standard on certain models, and the ones that have it have a 12v LFP battery for all other low voltage controls and then a separate 48v battery for the PDCC. So if you have for example a Cayenne Turbo S e-hybrid the vehicle will have a 12v battery, a 48v battery, and a Hybrid HV battery. Even the Mercedes Mild hybrid 48v system that was introduced in 2017 still has a 12v battery. That's the catch, however unless a knowledgeable Tesla employee chimes in the CT system could be like that as well, only time will tell. If it is a true full 48v system I have a bunch of questions

I thought I saw a gear selector in the overhead console?

Could be something like the refreshed MS. Still find it strange that there is not more out there on the interior and UI…
Actually - per a recent video that I saw - oddly enough you can also switch gears up on the overhead console. Go figure.

Yep - I drove a 1989 Honda Prelude with 4WS for a few years back in college. Nice ride.
If it’s anything like the gear selector in the model S/X, it’s incredibly unresponsive. Really can’t rely on it for day to day use. It’s truly an emergency only system.
Mine appears and disappears. Kind of fun to see the unexpected at times. Just of like the auto park prompts!

That's kinda, "fugly" looking....Actually - per a recent video that I saw - oddly enough you can also switch gears up on the overhead console. Go figure.

rear wheel steering is nice but not "cost savings" and
Tesla is first there. Just one word (and the long review from Cammisa mentioned that) ... steer-by-wire makes it easy to maneuver a massive vehicle like a truck at low speeds.... but you lose a lot of "feedback" and the steering is more indirect compared to a physical connection. in a sporty , smaller vehicle like the S or 3 ... steer-by-wire wouldn;t necessarily be a good thing for the driver.
From all of the reviews there's a learning curve with steer-by-wire, even for a big truck like the CT.
agreed. I like the concept but have a hard time seeing it being remotely direct enough/ enough feedback for a sports car or more sporty vehicle. Maybe that's why Lexus is working on it but not BMW.

Not really...
From Wikipedia:
Production vehicles[edit]
Up-fitted drive-by-wire systems, such as the Paravan Space Drive, have been available since as early as 2003 for existing production vehicles.[9]Coupled with traditional steering[edit]
See also: Steering § Four-wheel steeringRear-axle-only steer-by-wire may be coupled with traditional front wheel steering for conditional four-wheel steering, reducing turning radius at low speeds and increasing stability at high speeds.[10] Purely mechanical four-wheel steering systems have been available in production cars since the 1980s, with computer-controlled electronically-actuated rear-axle steering becoming available shortly after. Car manufacturers that have offered rear-axle steering in the 2020s include Acura, Audi, Bentley, BMW, Cadillac, Ferrari, General Motors, Genesis, Lamborghini, Lexus, Mercedes-Benz, Porsche, and Rolls-Royce.[11]
One such rear-axle-only steer-by-wire system couple with traditional front steering was Quadrasteer. It was developed by Delphi and was offered starting 2002 on some General Motors trucks. Despite favorable reception the system was discontinued in 2005 due to poor market penetration of only 17 percent of sales of the same model, partially due to lack of familiarity with the system and partially due to its $1000 mark-up.[10]
Rolls-Royce vehicles based on the Architecture of Luxury platform, such as the Cullinan, Spectre, Ghost, and Phantom, have computer-controlled four-wheel steering.[12] The front wheel steering uses electric power assist[13] while an electronic system controls the rear wheel steering and turns them in the opposite direction of the front wheels when turning at lower speeds, and slightly in the same direction as the front wheels at higher speeds in order to increase stability.[14]
Without traditional steering[edit]
Steer-by-wire without the use of a steering column was first offered in a production car with the Nissan Infiniti Q50 in 2013.[4] The system has a backup steering column separated from the steering wheel with a clutch. The clutch connects the steering wheel to the steering rack in case of failure of the electronic steering sensors or actuators.[2] After negative reception the model was retrofitted with traditional hydraulic steering.[15] Steer-by-wire continued to be offered with the QX50 and QX55, and as of 2022 is being offered with the Infiniti Q60 coupe.[16]Electric vehicles[edit]
Production battery electric vehicles (BEVs) with rear-axle SbW coupled with traditional front-wheel steering include the Rolls-Royce Spectre[17] and Lotus Eletre.[18]Production BEVs with steer-by-wire with no steering column include the Tesla Cybertruck.[19] Planned production vehicles with no-steering-column SbW as of 2023 include: Lexus RZ 450e,[20] Toyota bZ4X,[16] Canoo Lifestyle Vehicle,[21] REE Automotive P7-module-based vehicles,[22] and Geely Super Van.[23] As of 2023 Lotus,[18] Mercedes-Benz,[24] Nio,[25] and Peugeot[26] plan to offer no-steering-column steer-by-wire cars in the mid to late 2020s.
