One of the reasons for a physical steering linkage is "steering feel", that car enthusiasts are always talking about, and complaining that Tesla's already don't have enough feel for them. If you removed the linkage entirely and went totally "drive-by-wire", then you'd lose the subtle input feedback that they're looking for.

There are actually TWO reasons you have to maintain mechanical linkage. The most important difference between an aircraft and a car is that the aircraft has redundant systems and a swarm of FAA-licensed technicians keeping those control systems working. The car? Not so much. If you can be reasonably sure the consequences of deferred maintenance won't leave you falling out of the sky, you're probably going to defer the maintenance. But to your point, yes, you'd lose wheel feedback, unless you're willing to give back all the weight the steering shaft saves you by adding a feedback motor!

@superchargerone

Nope. Unlike aircraft with their mandated high cost maintenance schedules, many budget conscious hamfisted car owners will do as little maintenance on their vehicles as they can possibly get away with and only replacing things when they actually break hence the so many regular breakdowns everywhere. So you would really want to have a physical connection to the rack.

Sandy can talk about efficiency and savings and be fully correct about them, but there is a cost in human life with these decisions that is hard to quantify.

Aircraft have multiple redundant systems for flight control, I'm not sure you would actually save any weight with drive by wire when you factor in the required redundancies. It would certainly help a lot with packaging, and allow for tuning of steering response. I personally would prefer to have the mechanical connection between the steering wheel and steering rack.

An observation for Sandy: An unpowered aircraft is either a glider, a crash about to happen or it's parked. An unpowered car with a steering system that's only electrically driven would be a PITA to move around a workshop or off the road during a breakdown (major power failure from a variety of causes). I vote we keep mechanical steerage with all our cars please 😉

A sledge hammer and muscles to tear down the front brake rotors seem to need multiple persons to work it off. WELL Done Munro & Associates .. GREAT TEAMWORK IN ACTION. I wish that all industry's could learn from this example. Git 'er done seems to be the mantra of this company and keep promoting your staff by highlighting their methods. Another fabulous video worthy of watching until the end.

Sandy, Thanks for showing the universal joint on the steering. No fly by wire, yet!

For most of us watching these Model S Plaid teardown videos, it is an aspirational exercise given the price point of this model. However, what should get us all excited is the Tesla practice of migrating over time many of its new designs & tech from the S & X to the Model 3 & Y which are realistically affordable by most of us. Huge unit cost savings are attainable when issuing a PO for 1 million components versus just 100,000. I personally am hoping to see a higher quality suspension in the Austin Model Y.

... allways great to listen to guys who know the stuff they're talking about 👍🏻

Sandy suggested saving weight and losing the drive shafts by having in-wheel motors, but that does increase sprung mass which has a whole lot of other issues.

Sandy I like the fact you are an empowering leader. Great to hear from others in your team.

I’m down with drive by wire steering (similar to aircraft) around the same time auto maintenance and regulations also match up with those of aircraft.

Also, there are plenty of aircraft that still use mechanical connections to their control surfaces.

Some controls can be moved manually, meaning without power assistance, although still through the hydraulic system.
