But he also said only the steering wheel physically controls the car. Surely the pedals stop and go?
Anyhow I deleted my post because his made no sense
Are we being forced to go electric?

really - this is what he said....He does not say ONLY the steering wheel controls the car
so the only physical controls steering wheel, stalks and pedals

Whatever, maybe I misunderstood this bit then which he said…
And even those, it is only likely to be the steering wheel which has an actual physical control of what the vehicle does
I’d only just woken up so it’s possible

And to be fair, the pedal isn't actually physically moving anything. It's just a switch. The wheel is likely to be the only physical mechanical device.
You do realise that EVs are far more reliable than ICE cars already, as they have so few mechanical parts that can break down?
but he doesnt state Moving, he states CONTROLLING...the pedals control speed and braking

No, I think you understood OK. I don't think the pedals will be actually directly physically controlling anything.
Even on ICE cars, quite a few modern ones have the throttle using "fly by wire" rather than an actual cable, and on EVs with regenerative braking, it will be electronic controls which determine how much (if any) of the force you apply to the pedal goes to the actual brakes.
Yes, those things I mentioned are things the driver acts on physically to control the car - but with only the steering usually being a direct physical connection between the control and the moving parts of the car.
right - so the accelerator pedal and brake pedal control no physical parts at all right?? hmmmmmm....so the brakes dont slow the physically moving wheels and the accelerator doent control the speed of those moving wheels.....
so when you get in the car, you switch it on via the key and off it goes without touching the pedals?? i'm not sure you got that right to be honest.
I mean the steering wheel only controls the direction of travel...not the physical movement of the car or momentum of the car.....brake and accelerator pedals do that.

I'm trying to distinguish between things where there is an actual physical connection between the control and the physical moving parts of the car, and those where the control actually operates some electrical process which then commands the moving parts of the car.
The steering is entirely physical in every car I'm aware of, and so are the brakes in all ICE cars I know of (foot brakes at least - electronic "handbrakes" have become commonplace). The throttle always used to be, but is becoming an electronic control far more often nowadays.
The brakes will no longer be a direct physical connection in an EV which uses regenerative braking.

Even for an emergency stop?

I don't think they can be. If the computer is going to decide how much of the effort applied to the pedal goes to the regenerative braking, and how much goes to the brake callipers (often none), then there really can't be a direct physical connection between the pedal and the callipers the way there is in most cars currently. It will still be the computer which controls the application of force to the callipers.
Actually, thinking about this further as I write, doesn't ABS already work by electronic control of the force applied, so even most ICE cars are no longer directly physically controlled by the force from the pedal.
My car does emergency stops by itself. So no - the footbrake is not physically connected with the brakes AFAIK. It just tells the computer to apply the brakes.

Yes, as a man of science, engineering and computers, I'm well aware of the benefits of EVs . Fewer parts is only one improvement; entirely rotary drivetrain (no reciprocating pistons, con rods or valves), and various other design features are huge improvements over ICE equivalents.
And yet driver/owner surveys show Tesla as a brand with low reliability, poor build quality and a high rate of safety recalls.
(19 in the States for the Model 3).
The number of recalls seems to fall each year, so perhaps the brand is improving, but I'd look at another brand if I was buying, and hope to avoid early-adopter pitfalls.
I won't buy an EV for another 4-5 years, so hopefully all EVs will be better by then.
The recalls are tiny, mostly software updates. There have been some tiny mechanical recalls like tightening a seatbelt bolt on the left side rear seat.
The build quality from the early 2013-15 Model S weren't that good. Since 2017 and the release of 2019 model 3 quality has been far better. I would say comparable to any other manufacturer.
No vehicle is perfect. I've had minor issues with our Tesla, but nothing that has interrupted the driving or taken the vehicles off the road. Our model 3 had a creaking top wishbone joint. Arrange via app, parts confirmed with service centre, done in an hour.
Bear in mind this is a company with only 10 years of making production vehicles. The legacy manufacturers have been at it, some over 100 years and still can't make a decent fault free vehicle. I could easily find any manufacturer with recall issues
You're clutching for excuses.
I was surprised to see our model 3 has over 55k miles now. It's used all week, doing 150-200 miles per day.
