So a rich person buying a powerful ICE supercar is fine and will not crash it.
But a rich person buying an EV will crash it
The desperation to find flaws in the 'EVil masterplan' is getting a bit tragic now.But a rich person buying an EV will crash it
This is the second thread this year started by someone claiming electric acceleration is very dangerous.
Sorry Rob
What power level is acceptable to you?
How about an X5M?

There's something quite incredible about how EVs can get the power down. It's clearly as a result of the constant torque that GT9 explained earlier, but it is quite spooky.
Just been out for a spin in my wife's new Cupra Born she got yesterday. It's only 204ps, but the way it gets the power down instantly and without a hint of wheelspin on a wet road is bizarre when you've been used to ICE. My E350d is quicker on paper, but it would not be able to get the power down to accelerate at anywhere near the same rate as the born below 40mph. Witchcraft

How do you decide who does get to drive them? Is an 'average punter' who saves up and buys one OK? At what point does he or she qualify?

I extracted this plot some time ago, i think the EV is actually the Born, I can't remember for sure.
The ICE is probably a Golf GTI.
The chart shows what you are experiencing, which is essentially the addition of kinetic energy in the most efficient way possible.

But a Model 3 performance is easily accessible and still pretty quick, not that I agree with the sentiment at all. https://www.youtube.com/watch?v=z-ue1ZzaWgM

I will add though that it was an incredibly easy car to drive slowly if you've got any control over your right foot. I can't say the same about any number of lower performance ICE cars I've had over the years.

By average, I'm referring to those who have no intrinsic interest in cars, and treat them as another commodity purchase, just like a washing machine. It has been mooted in the past that graded driving licenses been introduced, but a bit too late for that now, the horse has bolted.robinessex said:

But they don't generally stamp on throttles. As we can see from the way they drive their i10s.
Are you worried about a granny or grandad jumping into an X5M and stamping on the throttle? Or just an EV?

I actually find on the whole I drive slower in a faster car as I know a stopping for a minor inconvenience is remedied by quick acceleration when the road is clear. I've been more impatient in slower cars where having to slow down and go through all the gears again to get to cruising speed feels like a hassle.

I have diddly squat interest in EVs, but the power outputs 'worry' me. Any PH knows a Lambo Aventador with circa 700bhp is bloody fast, and even with TC, needs some respect, caution, and I dare I say, skill. Yet anyone can pop into a Tesla showroom, and come out with a model X with 1000bhp, with a 0-60 time of 2.5 secs (1g). I hope its got some bloody impressive CT preventing Sharon, in a late dash take taking kids to school, doesn't floor it on a wet greasy road, and ends up inverted somewhere. Why not limit the power output to extend the range? I'm also puzzled about how the insurance companies are handling this. Henry is lurking in my garage with 400 supercharged bhp, he can be a bit naughty if you get a bit too enthusiastic. Don't ask me how I know.

Those people aren't going to buy an EV with 1000+hp though In anycase, whatever your fears, the reality is they're not actually leading to more incidents/crashes in the real world. EV insurance costs have been reducing over the years relative to ICE as the underwriters have gained more data. Many EV's are now cheaper in terms of insurance than their ICE equivalents - probably because of the supreme levels of traction they can deliver and maintain making them slightly safer in some situations.
It strikes me as odd that you should be worried about a something that has already been proven to not be the case.

Every time I wanted to do 0-60 in 2.3s in my Tesla Model S, I had to select Ludicrous+ and then wait 45 minutes for the battery to warm up. Plenty of time to consider the consequences of my actions and prepare for the g-forces. I think once in 3.5 years I had the patience.
In my RS6 Performance I had before that, you just floored it and off it went, regardless of when. Throw in gear changes which could cost you grip and stability and I would argue the RS6 was more dangerous and the performance was more accessible. Albeit 1s slower or something to 60.
The Model S is gone now and I am back to petrol until they build more chargers...
I didn't have to wait for the battery to warm up when I did 0-60 in sub 3 seconds in a Lucid Air. You just floor it and off it went, and it goes round bends better than any Tesla, imho. I would argue that EVs inherently feel more stable and planted when accelerating than ICE vehicles due to lower CoG.

The Lucid Air Sapphire they had in the showroom but not available for test drives has 1,200bhp and does 0-100mph in less than 4 seconds (allegedly)
If a 1,000 bhp Tesla has got the OP worried and sitting there ruminating on anxious thoughts about hypothetical scenarios, I suspect the Lucid Air Sapphire might make him worried enough to start a new thread somewhere.

The company attributed the higher damage from crashes to what it called “the overtapping effect” that causes electric cars to accelerate far faster than their conventional counterparts using the same amount of force on the acceleration pedal. The “overtapping effect” is “likely to be the reason for the increased claims frequency for high-performance electric cars,” the company added.
“Most electric cars, especially the powerful ones, have a very high torque, which is immediately noticeable when you tap the power pedal. This can result in unwanted, jerky acceleration, which the driver can no longer control,” said Michael Pfäffli, HEAD OF ACCIDENT RESEARCH at AXA Switzerland.

Lotus Evija 1500 kW (2011 hp)
Aspark Owl 1480 kW (1984 hp)
Pininfarina Battista 1417 kW (1899 hp)
Rimac Nevera 1408 kW 1408 kW (1887 hp)
It's easy to see why this is happening too. Power is extremely cheap in EV terms, on several levels: Larger more powerful motors are only fractionally less efficient, and not a huge weight penalty either, also not particularly expensive vs a smaller motor. There is very little efficiency lost by giving an EV 1000hp vs giving the same EV 200hp, driven the same way, the two will offer roughly the same efficiency - that's obviously very different in an ICE car with 1000hp, which would be inefficient however you drive it.
Even the brakes on a fast EV don't need uprating to the same extent as they do on fast ICE cars because the regen is providing such a large chunk of the braking effect.
