No idea, but I think that all BBW systems still have a physical connection? I don't think any car uses a true BBW system which has no connection between the brake pedal and actual braking system yet.

Just wondered whether it could possibly be an actual failure somewhere or just some attention seeking weirdo / user error like a lot of these things turn out to be.

I’m calling bullshit.
Let’s assume it’s true that it both locked on full throttle and wouldn’t shift from drive to neutral. I refuse to believe that the mechanical brakes also refused to work.
I accept that - if you don’t really understand how brakes work - you could squeeze them and get everything so hot that it might feel like they aren’t there, but a couple of miles at 100+ will cool them sufficiently that I’m confident they could bring the car to a stop even with the power on.
Mrs mik’s e-trim has four pots & LARGE vented discs on the rear, with whopping great 6-pots on the front grabbing mahoosive vented and floating discs.

I'd be checking the floor mats first.
Good work by the Police though. Could easily have ended up stuck in a lane with a high risk of being rear ended.

I'd be checking whether they'd been accidentally using the brake pedal as a footrest, too.

This isn't the first time is it? I remember a similar story before that turned out to be BS when the driver claimed the accelerator was stuck down when it really wasn't.

Ah, I listened to the podcast;
That wasn't perfect (as they didn't fully explore how you can move the car from in-gear to neutral, or how you can switch off the engine, or how the vast majority of cars cut off the power to the engine if they detect simultaneous inputs from both accelerator and brake) but it was very good. Cheers.
It's a sad indictment on the US legal system that conclusions are drawn in one case and "everyone else" barrels in behind, leveraging that conclusion - despite the complete lack of evidence that the issue claimed actually occured, and despite the overwhelming evidence that it didn't (eg logs showing that the brake wasn't depressed).

Also worth noting that after 3 years of full access to Toyota technology, the plaintiffs were unable to reproduce the sticking throttle, including trying to trigger software bugs they claimed to have found (and the black box logging showed these supposed bugs had never ever been triggered).

Yep. Total bullshit. Wife told me about it a couple of nights ago and that was my first response. And AFAIK the i-pace is a fully hydraulic braking system, so no BBW. It will be user error in some way, shape or form.

But, but, but someone (else) has to be responsible (and more importantly, liable!)
