No creep - the car doesn't move if the accelerator isn't pressed
Creep - the car rolls forwards if the accelerator isn't pressed
I agree that (on the roadster) the creep disappears while your foot is on the brake pedal. This can be seen by the power draw. So a smooth stop should be possible, and indeed as far as I know I always manage smooth stops in the roadster. Also, a few posts back, someone mentioned a clutch; there is no clutch in either car; when stopped, the motor is doing 0 rpm.Originally Posted by Sparrow
Yes, the Roadster turns off the motor when you're at a full stop with the brake engaged. Find a hill that's just steep enough to negate the creep, and you'll see there is more current draw when you're off the brake than when on.
But this proposal is different; it's suggesting that as soon as you push the brake the creep would be turned off, not just when the car is stopped. Lift off the brake and the creep will reactivate (as it does now). I do believe I would vote in favor of the proposal.
Certainly can't be any creep when your car is doing regen braking so it would seem that at most this could only be a problem during very very low speed driving.
I like the creep feature. Works great in slow traffic.
This is an easy fix as car manufacturer's have a solution for MT ICE's. Some cars have a Hill Assist feature which applies the brake for a second (or something like that) to prevent roll back for when you transfer from the brake to the gas and shift into gear. I believe even some AT ICE's have that, so I don't see why Tesla couldn't implement that in their cars.
As to creep, when I drove Slackjaw's Roadster last Saturday I'm pretty sure I was able to bring the car to a smooth stop a good portion of the time. If I didn't it was probably because I was trying to come to a stop a little quicker. Of course I haven't had nearly as much drive time as you guys. But as someone who drives a MT ICE, I would much prefer no creep and hill assist. I also don't see why (if Tesla did implement the creep for safety reasons) they coudn't add a sensor in the driver seat so that when it is not depressed for x amount of time the car could shut off or make some audible noise to let the driver know the car was on and/or it was turned off. Depending on how the car is set up I don't see why it wouldn't be able to send a text and/or e-mail to let the person know.
That's just my 2 cents and how I would prefer it for when I can eventually get a Tesla.

Stuart, I am absolutely, without-a-doubt in agreement with you. The automatic creep must be either user-selectable via a preference or in any other fashion possible to override. Having driven a MINI E for two years, I am addicted to the smooth stop possible without creep and privately anguish every time I can't get my wife's automatic ICE to do the same.
Okay, I exaggerate a bit, but in seriousness, I do find driving an ICE annoying due to the creep and hate that little lurch when the brakes finally seize the vehicle. The Model S needs a preference to turn off the creep.
Yes, the car will stop, but it takes more brake pressure to compete with the motor trying to drive it forward. Notice I said I want to be able to bring the car to a smooth stop. For people who've only every driven automatics and have never experienced a car that can stop without a lurch, I understand that it's hard to sympathize with what I'm asking for.
There's a nuance here that I think some people are missing. I agree with Stuart.
Creep shuts off at about < 1 MPH and when that happens and you're on the brake, the car comes to a sudden jerky stop. It happens to me every time I casually come to a stop. It's poor experience and lacks refinement.
Creep doesn't need to be shut off when the car comes to a complete stop. It could be left on for a second after a complete stop, or just left on at all times. There's not that much power flowing so there's so little power consumed and heat generated, it can't possibly be an issue.
I wish I'd brought it up while I was talking to the engineers at the factory!

That's what the hand brake is for! Americans call it the "emergency brake" and think I'm weird for using it every time I stop at traffic lights, but anyone who passed the "hill start" part of the UK driving test (especially in a manual car) should know how to use it. In a manual car, if you don't use the hand brake, then when you move your right foot from the brake pedal to the accelerator (remember your left foot is occupied pressing the clutch pedal) you're going to roll backwards on a hill if you're not using the hand brake. It's second nature to me, but I'm used to driving manual cars. For me, the skill of balancing the clutch, accelerator and hand brake so that you can move off smoothly (without rolling back at all, even on a steep hill) is just as important as the skill of being able to stop smoothly.
Here's an experiment you can try for yourself, in an empty parking lot when you can experiment safely without other drivers around.
At a low speed, say 10mph, put the drive into neutral and experiment with gentle braking until you can consistently bring the car to a smooth stop with no lurch. In the final few seconds before the car stops you'll need very light brake pressure to do it perfectly.
Now, once you're able to do this consistently, try it with the car in drive. You'll find that no matter how careful you are, the lurch is unavoidable. I suspect that once you've mastered the skill of the perfect smooth stop it will start to irritate you that you can't do it with the car in drive.
