Gauss pedal? I thought I settled this. In F1 they call it the torque demand pedal. Who would be a better authority?On a Tesla, N is exactly the same as pressing the gauss pedal however much is needed to accelerate/decelerate at the same rate.
On a fossil car, N might use more or less gas than staying in gear, depending on the conditions and auxiliary loads.
On any car, it is foolish, risky, and illegal to coast in N.
I'd say that if you could shift the car into reverse when driving down the freeway at 80mph you might well over-stress the motor and generate a LOT of heat that could cause damage.The 5mph limit when shifting between any gear is for your own safety, the car couldn't care less. The warnings are just to help you avoid mistakes.
"Gauss" pedal is a fun name (sounds like "gas"!), but of course Gauss is not the SI unit in question, it's (ta-da!) "Tesla" (really).Gauss pedal? I thought I settled this. In F1 they call it the torque demand pedal. Who would be a better authority?
No. You can’t consume more fuel in N than when you’re idle. Same as if the vehicle was stopped. In gear, you feel the vehicle trying to slow itself down so you’re wasting more fuel that way because the transmission forces the RPM to go up a bit. So with the RPM going up, more gas is used. This varies across different vehicles. So N saves gas.I thought shifting to N on an ICE car actually consumed more fuel because instead of the momentum from the wheels turning the engine, the fuel pump is engaged to idle the engine. When in gear and coasting an ICE vehicle will typically not send fuel to the engine.
Not if the ICEV has deceleration fuel cut-off, in which case going down the hill in neutral requires fuel use to keep the engine idling while going down in gear allows the engine to be driven by the wheels without any fuel use.In an ICE vehicle you can always go from N to D while going downhill without any consequences. In fact, it is a good thing to take a down hill and let the car go to N while letting the gravity drive you down if the ICE car has a manual transmission since that saves a bit of gas.
This is why I said, it varies across vehicles. For instance, if it’s a hybrid, then driving downhill in N would cause the engine to shut off, but it is a bad idea because then you don’t get any regen braking. Although, a hybrid will always shut off the engine in a downhill whether you’re in D or N.Not if the ICEV has deceleration fuel cut-off, in which case going down the hill in neutral requires fuel use to keep the engine idling while going down in gear allows the engine to be driven by the wheels without any fuel use.
Is the transmission being lubricated when coasting in neutral on modern ICE cars? There has not been rear mounted pumps on automatic transmissions in more than 50 years.This is why I said, it varies across vehicles.

Another gear tip. Many first time Tesla owners come to a full stop when going from R to D. Try this... reverse at any normal speed when getting out of your garage but do not press on brake or let go of the throttle when time to shift to D. Just tap the stalk and go to D. Notice how it smoothly slows down and then changes direction...
I don't think it's a joke. It happens to me too in some parking lots, trying to switch between Drive and Reverse (or vice-versa) and the car screams at me without doing the change. By instinct I press the accelerator and it doesn't do what I want. I must be at 6mph when that happens I guess as I'm not going that fast... but you get used to this being normal and it screws you up when it doesn't to it. Borderline dangerous to NOT switch gears when I ask it to and rely on that change.You're joking, totally unnecessary edge case.
I just call it the “accelerator pedal”."Gauss" pedal is a fun name (sounds like "gas"!), but of course Gauss is not the SI unit in question, it's (ta-da!) "Tesla" (really).
"Torque Demand Pedal" sounds like it was invented by one of those people who thinks saying "affirmative" instead of "yes" makes them sound smart.
With 2023.12.1 and up, there is an option to enable gear-change chimes. Might be annoying but it is informative.I don't think it's a joke.

"Car Go Faster Foot Operated Press Down Thing" (to steal from Randall Monroe)I just call it the “accelerator pedal”.
I like calling the brake pedal "the stoppy thing". (To steal from the Star Wars Muppet Show episode.)"Car Go Faster Foot Operated Press Down Thing" (to steal from Randall Monroe)
My guess is that it is also a protection thing. Shifting from D to R at higher speeds is going to put a lot of stress on the motor, as the rotor will be moving in one direction while the magnetic field is trying to drive it in the other. That will generate LOTS of heat and mechanical stress, which is probably not good for the motor long term.This is a subject that is incredibly difficult for those who still think in ICE. As a couple of people have noted, there is no 'shifting' as known in ICE. Of course there is regenerative braking in most BEV models so one rarely needs to use brakes either. What our logic says is 'shifting' is software changing from one direction to another, no 'shifting' happens either. That is also why 'neutral' does not exist as it does in ICE, 'neutral' just stops power to the motors.
That is also why 'shifting' from 'D' to 'R' is limited in speed to protect drivers, not the car, the motors really do not care.
