And the clearly visible exhaust pipes…and the E-pace badge. Who’s going to break the news to the anti-EV twitchfork mob?…

It could be a hybrid though

Ahh the Daily Mail.
Hybrid Jaguar goes 'rogue' and reverses into a Porsche
Business owner Andrew Key was powerless to act as his £47,000 Jaguar E-Pace suddenly reversed at speed into a Porsche Boxster parked behind him.mol.im
Still got an engine and gearbox. According to the article, Jaguar investigated and found no faults with the car, the police attended and the driver got a penalty. Suspect this is the driver trying to recoup his fine by way of a fee from the DM

It is....
OK so with the engine stopped (as the driver claimed) it's just as capable of uncommanded movement as a pure BEV.
I don't think it's very likely, but it's technically possible. Whereas if it had been an ICE then the driver would clearly have been talking b011ox as there's no way those can move unless someone starts the engine first.
As above the point is that anything with electric drive can theoretically move at any time so long as there's power in the battery. A pure ICE can't unless the engine is running.
How capable of that is a pure BEV anyway? If you are talking about the ability to auto park/move out of spaces etc then I believe there are ICE cars that will also do that.
The EV needs power in the battery and for the circuits to be live to connect that power to the motors and for the control systems to activate the motors to turn. An EV won’t move just because there is charge in the battery any more than an ICE will move because there is fuel in the tank

My money is on user error......like 99% of the similar stories.

I don't think it's been made clear whether the engine was actually running or not?
Also, when we hear about 'unintended acceleration' coupled with "I stepped on the brake pedal as hard as I could but it had no effect", then either the car suffered two unrelated catastrophic faults at the same, or the driver is simply unwilling to accept (or admit) that he/she stepped on the wrong pedal. I think you can work out the probability of either option....

Mine too.
But 42 years working in IT taught me that it's essentially impossible for complex software to be bug-free. Even with almost 'no expense spared' budgets (as NASA and various aerospace companies have demonstrated several times).
In the original article the driver claimed the engine was stopped.
To be clear I'd put money on him being at fault in some way. I'm just saying it would be technically possible for a hybrid to move suddenly and unexpectedly (e.g. due to an electronic or software glitch), so long as the drive battery isn't flat.

An electric motor that is controlled solely by software can theoretically start (or stop) at any time. It's not likely, but it's technically possible. Whereas as mentioned once an ICE is turned off the vehicle ain't going anywhere (so long as the parking brake holds).
Try (or rather, don't....) the following:
Car in D, stopped, with ECO start/stop kicking in and the engine not running.
Activate the brake HOLD.
Remove all feet from all pedals.
You now have a silent car, with the engine 'switched off'. A distracted driver might certainly think it's fine to leave the car now, forgetting to switch off the engine properly.
Now undo the seatbelt....... and you have a vehicle moving forward autonomously.
Get startlef, and hit the brake pedal with all your strength. If you happen to panic and hit the accelerator by mistake, there's your 'unintened acceleration'.
An electric motor is not required.
Wait, undoing the seatbelt causes the engine to restart and brake hold to release?! Even then the car would only creep slowly with the engine idling - unlikely to evoke a panic response from the driver?

The irony. A CO2 rich atmosphere helps crops grow in abundance.

Well, if you have a better explanation, let's hear it
What gets me every time I read these articles, is 'the brakes had no effect'. The likelihood of complete brake failure at the same time as another catastrophic failure is one in a billion (wild guess).
