The driver who planted one in a front garden near me in the snow wasn't. Didn't comprehend that lots of go didn't equate to lots of whoa.
And that's specific to EV's of course, or indeed the amount of go.

Good question. From the clips on youtube, seems as if quite a few aren't. But Lambos, and others, do project speed and power, so I assume potential buyers are well aware of what they've got. However, if Sharon jumps into hubby's 1000bhp, 1g acceleration EV, to pop down to Tesco for some milk, I'm wonder what an inadvertent prod of the right pedal would result in?
Misogynistic much?

You need to stop thinking of EVs as some kind of other transportation method.

EVs are a car, same as a Lamborghini is a car. They happen to be a powerful car in some case, but still a car nevertheless.

If someone buys one, they know what they are getting and they will advise anyone else who drives it what it's capable of.

Many moons ago I was sat at the lights part way round a big roundabout, with the next exit a two lane going onto the motorway. A Tesla pulls up next to me. Lights go green, I launch it pretty quickly but normally (my car is quick'ish but never going to trouble anything fast) and somewhat to my surprise leave the Tesla behind. Mr Tesla obviously napping gets a massive bee in his bonnet about being beaten off the lights and absolutely hoofs it, straight passed me ... and goes *VERY* sideways on the corner on the motorway sliproad. He was saved only by the stability control (and still nearly clipped the barrier).

Very much a case of being unable to control the power/acceleration of his car (coupled I think with a "how dare I be beaten off the lights" mentality).

If only it was limited to EV drivers..

I came of my push bike twice in snow and ice in December, clearly way too much power hehe

One thing I've noticed about my Tesla is how superb the stability control is, even driving like a hooligan in the wet I can barely get any sideways movement either in our out of the corner. Actually it's one of the most impressive bits of the car.

Drivers routinely overestimate their driving skills (regardless of fuel type) and I suspect if you removed all sorts of passive safety systems like skid detection, blah blah blah, there would be many more people losing control of their vehicles at any speed.

Indeed. It seems to be about why women in Essex shouldn't drive their hubby's cars because they will crash them, and only macho men who have supercharged ICE cars can drive without crashing.

It's not 1000bhp though, is it?

Not in PH anymore. Many have nowt to contribute to the room title, so resort to pointless, off-subject injections.

Which 1000 bhp EVs give you access to that power below speeds where you can actually use it?

Quite. It's not the 1950s any more and women do drive cars. The suggestion seems to be that EVs are more dangerous because 'Sharon' might get to drive it rolleyes

I guess TC kicks in, but as pointed out a few postings ago, an EV can get out of control.

From Tesla website Model X

0-60 2.5 sec (+1g), "that maintains 1000+ hp all the way to top speed"

I don't think you've absorbed what I posted earlier.

It's got nothing to do with traction control.

It's inherent in the design of the drivetrain.

Here is the power curve for one of the most notorious 1000 bhp EVs.

Full power in NEVER available below 60 mph.

Crossposting from another thread. Essexrobin, it’s not the 1950’s anymore.

When mine faffs, things get reorganised / put in a different place [for no reason apart from 'the hell of it' from what I can see].

So we have 3 house phones dotted round the house for ease [Kitchen, Hallway, our bedroom], but MrsH decided without consultation [as is often the way] that "we" didn't need one in the bedroom anymore, so turned the charger off at the wall and stored it in the loft in its original box

What she didn't reckon on was that, although the charger was turned off, the phone was still charged and would charge down over time. Cue last night, 11pm, and every other minute a fairly soft 'beep.......................................beep' could be heard. We discussed this in the dark in whispered tones so as not to wake the children, and assumed it was one of the neighbours smoke alarm batteries running out - annoying but they'd eventually hear it themselves and sort it out - they're good neighbours so we let things like this slide smile

1am - let the dog out for its nightly ablution and still heard it.
4am - light sleep awoken by the noise
5am - couldn't sleep any more so was wide awake til 6 when I take the dog out for its morning walk

8am - after the dog walk and my shower, we were in our bedroom and I could still hear the beeping; MrsH 'couldn't hear it' but my daughter could and suggested it sounded like a phone running out of battery, to which MrsH suddenly remembers her tidying yesterday and opens up that perhaps its the phone she took out of the bedroom and stored in the loft....

For f's sake....
Put a oneway latch on the loft, the next time she ventures there, she won't be able to get out

I'm guessing that's what I enquired about, the motor control system limits current and volts. An electric motor will draw much more current when stalled than when running. This is because when running, it is also acting as a generator, creating an EMF which opposes the applied EMF and reduces the overall current. A DC compound motor can run in series or shunt configuration, a bit like underground trains do. IN a DC shunt motor, torque is proportional to armature current. For a series-wound DC motor, torque increases as the square of the armature current.

This is a fun one too, in the context of this thread. Keep dreaming in the nursery home, while yelling at passing EVs.

I'm hoping that all EV's come with auto speed limit control, thus they'll all be confined to the inside lane of a motorway as they won't be able to overtake each other. The outside lane(s) will now be totally traffic free for us old gits in our ancient ICE horseless carriage to proceed at a leisurely 1 lepton or faster, all the speed cameras having been mothballed long ago.
