Tesla test drive

Undertoad • May 19, 2016 11:27 pm
My boss took delivery of a Tesla Model X over the weekend and today he let us take it out.

0-60 in 3.2 MPH fuck yeah, and fuck yeah the boss let us put our foot in it. It's like... shot out of a rail gun. It's cray. And there's no throttle delay, it just takes the fuck off. It's a wild feeling and causes you to say fuck a lot.

Automatic driving - on the highway, take your hands off the wheel and your foot off the pedals. It knows. It's got this. Want to switch lanes, hit the lane switch stalk. A really wild introduction to self-driving cars. I couldn't handle it, I grabbed the wheel and took back over. That's fine too, it lets you do that.

Regenerative braking - take your foot off the gas and you feel the car saving the energy.

Double-hinged falcon wing back doors... a center screen bigger than an iPad and ready to roll Google Maps... you don't have to close the door when you leave it, it takes care of that...

It was like visiting the future. I can't wait for the 2027 Ford Focus to offer this shit!

Do you mean when you put your foot on the brake, or does it brake automatically when you lift your foot off the gas(electric)?

Acceleration will always be good because electric motors have full torque at zero rpm.

B - you take your foot off the pedal and immediately you feel a change, as if you're braking; Tesla says

Due to the simplicity of the AC induction motor’s single moving part, the Tesla Roadster does not experience the engine compression braking of a traditional internal combustion engine (ICE). Instead, the advanced algorithms in the motor controller give it complete control of the motor torque for both driving and regenerative braking. A torque command is derived from the position of the throttle pedal. The motor controller converts this torque command into the appropriate 3-phase voltage and current waveforms to produce the commanded torque in the motor in the most efficient way. The torque command can be positive or negative. When the torque serves to slow the vehicle then energy is returned to the battery and presto - we have regenerative braking!


The thing also has regular brakes but you hardly have to use them. You can slow down just with the "gas" pedal (now the "torque command" pedal I guess) and throw all that energy back into the battery!

OK, they've eliminated freewheeling in favor of regeneration.
I hope these bells and whistles like lane changing, and hands free, improve faster than the other things create more inattention.

I love these things but my gut says be nervous about ubiquitous hackable electronics.

Me too. Almost word for word.

I'm almost 50 and according to the rules, it's almost time for me to start fearing change and new technologies. And those teenagers over there.

Tesla is not Detroit. Tesla has smart people working there, so if anyone can pull this stuff off, it's them. But still. I'd like to be able to take control of my car if it starts behaving strangely.

We've discussed this when there were those sudden uncontrollable vehicle accelerations in the news a few years ago. Turns out the gas pedal and gear shift are no longer manually connected to the car. They are just switches and are only massive to make it feel like they are connected to something. But they are switches that connect to the computer. That Jeep that was hacked a couple years ago and shut down on the highway shows that Detroit doesn't really understand electronics and software. My cousin's fucking Ford won't start because the car doesn't recognise the chip in the key. A key that will open the doors and will turn in the ignition. (I still need to get that fixed.)

But Elon Musk is different. I'm hoping he is our savior. I know he values intelligence and innovation, and he's perfecting so many different new things. I hope Tesla can pull this off.

Did we? Because IMO every time it's investigated it turns out to be pedal misapplication, like the original Audi story

and that turns out to be fixed by taking the decision-making process out of the hands of humans.

About 35000 dead every year from accidents, mostly human error... the only question is can the cars do better...

Because the thing is, the car was driving better than I was, when I took it over... I increased the chances of an incident by insisting on driving... I am more susceptible to mistakes than the Tesla, which so far hasn't made any...

My recollection was that the majority of the time it was blamed on mixing up the brake and gas pedal, but that there were a few troubling cases that still didn't fit that explanation.

We discussed it in this thread and there was never a link to a final official report, but Flint said he heard on the radio that 74 of 75 Toyota cases were blamed on driver error.

I think the answer is YES. Cars can do better. Absolutely.

For a time, anyway. What happens when the car ages and the systems fail?

Ford Motor Company is recalling 746,842 ... vehicles ....

The coating on portions of the Restraint Control Module (RCM) may crack, and when exposed to humidity, circuits on the printed circuit board may short. The short circuits could cause the frontal air bags, side curtain air bags and the seat belt pretensioners to malfunction when needed, increasing the risk of occupant injury in the event of a crash.


Once the cars drive themselves, the Autonomous Drive Control Module circuit board may also suffer from a cracked coating and moisture infiltration after a few years of use may cause shorts. What if the first sign of such a problem is the car suddenly swerving off the road?

Or the Collision Avoidance System slams on the brakes at 80 mph in interstate traffic?

I don't like automatic stuff. Not on my computer. Not on my car. And not on my car's computer.

Those are problems you thought of off the top of your head, so those are the first things the engineers considered, ten years ago, and already have a strategy for!

The actual problems will be things we couldn't imagine. Unique failures that were unpredictable.

Control Panel -> Administrative Tools -> Services

(Do not change all those "Automatic" things to "Manual". It will break your system.)

So, what are those strategies to keep those electronic doodads from shorting out and surprisebuttsecksing us to death on the freeway? I haven't heard anything about safeguards on any of this automatic stuff. Like you, I'm sure they're there, but, I just haven't heard about them.

I'll bet that one of those strategies is to charge multiples of what a car is actually worth so they have money to pay off the lawsuits, when this automated shit hits the fan later.

I see in my Facebook feed that Google has applied for a patent to squirt sticky foam out upon impact with a pedestrian to glue the pedestrian to the car so they won't ricochet around the place.

So I'll accept UT's statement that the engineers are thinking about all sorts of different solutions to stuff I haven't even considered.
xoxoxoBruce • May 20, 2016 2:54 pm
Yes.
glatt • May 20, 2016 3:11 pm
Not just applied, it seems, but issued a patent. That sucker was granted.
Griff • May 20, 2016 3:44 pm
I traded the POS Mitsubishi Sport in on Pete's new Subaru. The anti-lock braking failed a number of times. My guess is the car is too light for its brake system so it locks out the pedal to prevent sliding. That is a shitty feeling standing on the brake with no effect at all. That is what happens when Detroit adds proven tech to cheap-ass cars. So extrapolating to Tesla's tech stick with Tesla on cheap-ass cars give me a mechanical connection I can work with.

We superstitious and stupid humans have ALL kinds of concerns and worries that go unanswered... but are simple answers for experts.

I feel like if we asked the people working on GMOs if they were safe, they would say "Did you think we didn't think of that?"
xoxoxoBruce • May 20, 2016 8:03 pm
You show an unwavering faith in the tech, even from profit seeking source's lowest bidders.
The cars electronics have been taught logic, if car 1 does a, do this, because there is 99.999% chance car1 will also do b and c next. If the computers are running car 1 this is true, but people do illogical things the program can't possibly predict.

Are GMOs safe? Define safe. Alcohol is safe. Aspirin is safe. Many things are safe with caveats. 'Did they think of that', is a non-answer to a non-question. The question is, if Monsanto discovered a long term problem, or even a possible problem, would they disclose it? Even though management's primary concern is the next quarter, and the problem wouldn't arise until their golden parachute has deployed, would they see their moral obligation to the people, like Philip Morris, R.J. Reynolds, and Lorillard?

This is what happens when you through people into the mix.

Man Claims His Tesla Model S Crashed Into A Trailer All On Its Own

Or take them out.

Seen on Route 270 near Gaithersburg yesterday on a license plate: A TESLA

And it was one of course.

Hi Katkeeper.
Katkeeper • Jul 12, 2016 8:00 pm
Hello! I had this funny desire to drive as close to the car to see what it did in reaction. Drive up behind it to make it go faster for instance. I have a feeling some people will actually try that.
xoxoxoBruce • Jul 12, 2016 8:32 pm
Sure, it's nice to know you can cut them off with impunity. ;)

A recent Tesla fatality involved an unpredictable hazard, as you say (something suddenly turning into the Tesla's path). The technology isn't yet at the point where we can kick back and stream a movie, but it's on its way. Until then we need to copilot.
Katkeeper • Jul 12, 2016 9:57 pm
I wonder if the engineers put them through tests where other drivers tried to control the Tesla's direction and/or speed with their driving. Tried to cut them off, tried to speed them up. Reminds me of playing with magnets.
