I'm not sure what is more disturbing here, the fact that the car had such a dangerous malfunction in the first place, the fact that there was no reliable hardware-based mechanism to bring it safely to a halt when the software failed catastrophically, or the fact that the service team could remote in and take control of the vehicle. Everything about this is not just bad in itself but betrays a more fundamental lack of safe and secure design.
- cevn 9y agoTotally agreed. Why can't he just slam the brakes? I thought they are supposed to be stronger than the engine?!

- olliej 9y agoElectronic control - it’s not a direct physical connection anymore. Follow on for mechanics/mechanical engineers: if the accelerator is down and you’re already moving, can the brakes stop a car? It seems like you’d either not stop or “break” abs and force the wheels to lock which is also bad at speed...
- vegardx 9y agoThis is complete nonsense, go into any car without starting it and pump the breaks.
- Skunkleton 9y agoIts not. https://en.wikipedia.org/wiki/Drive_by_wire https://en.wikipedia.org/wiki/Drive_by_wire
- tialaramex 9y agoThe ABS system is based on monitoring the way the wheels move and comparing it to how a car can move, in particular since the car is either moving or not, if just one wheel is stopping but the others are not, that's clearly wrong and the ABS tries to prevent that by reducing braking for that wheel. Going from some minimum speed to zero on all wheels is fine, that means now the car is stopped (or, for example, you went off a cliff and are actually now flying through the air - ABS can't help you in this case).
- ceejayoz 9y agoI'd really like to know what else the remote access allows them to control.
- olliej 9y agoI assume the entire ECU, that said maybe they treated it as stolen and triggered a remote stop through an anti theft mechanism?
- martimarkov 9y agoI mean even Formula 1 cars have the breaking system being outside of the computer control. Like we have totally solved this problem before. Why would you remove hardware override is beyond me... https://www.formula1.com/en/championship/inside-f1/rules-regs/Brake_system.html https://www.formula1.com/en/championship/inside-f1/rules-reg...
