Seems a little silly.
Do any UK HNers have thoughts on why phone theft is so common there? It’s not really a thing in the US (or hasn’t been for years), so I’m curious why it’s such an issue over there.

#12> Police already have technology to stop cars remotely using radio and electromagnetic waves. Never heard about this one. Anybody got a link, or even name?
Not sure. Radio waves are electromagnetic waves. They might be talking about stuff similar to OnStar.

#13Effect on pacemakers?
Hopefully none - human body is great at shielding things from EM radiation, and these things are already designed to be extremely resistant to external interferance for obvious reasons.

#14DC ("brushed") motors won't be affected by that, especially if controlled with no transistors. See for example how old DC-powered electric railway rolling stock was built, from pre-power electronics era.
Brushless motors have been the norm in e-bikes and e-scooters for a long time. And even modern brushed electric motors in EVs have electronic control via microcontrollers. There's no way you can get maximum power efficiency out of it without software control.
Of course. And no, you don't have brushed motors in modern EVs, outside of some DIYs. It's all BLDC. However, where have I contradicted any of this?

Would you be willing eat your words? Plenty of EV motor designs from Continental, ZF and Chinese companies are brushed (or other forms of physical shaft contact with slip rings). Not every EV is BLDC due to the desire to give up on expensive rare earth magnets on budget models.

'Carrier locked' phones are illegal here, and were uncommon before then. Much easier to reset these devices and move them on.

Or funeral

#18All e-scooters and most e-bikes are completely illegal on UK roads. Would be pretty amusing (and dangerous) to see this used on a busy street filled with hundreds of illegal riders.

High phone prices.
