Safety-wise it's better option.
Breaking vs just rolling without working brakes.
And I really do not like trend of making brakes drive-by-wire instead of mechanical just to (presumably) save few pennies...
- simondotau 3y agoThe Tesla Model 3 brakes are hydraulic and the pedal is still mechanically connected to the master cylinder. It’s the parking brake which is electronically actuated, as it is with nearly all modern ICE cars.
- seanmcdirmid 3y agoIsn’t the 12V battery responsible for that? It sounds like the driver lost that somehow, not the main battery.
- misnome 3y agoIs it? What if it runs out of power at 70mph in the middle of a motorway? I’d have thought sudden breaking would have been the most dangerous thing to do
- ndsipa_pomu 3y agoIt shouldn't be as emergency stops can be performed at any point in time - usually when there's an emergency. Obviously it's important that following drivers have left enough space so that they can react in time, but that's down to their driving skill (or lack of, if they're too close). I'd consider that autonomous vehicles should apply the brakes if they find themselves in an uncertain situation as reducing speed is going to minimise any impact. However, this was being driven acoustically and the handbrake shouldn't have been applied automatically by the power running out. At the worst, if a handbrake fails and can't be used, you can always shove a couple of bricks under the wheels to stop the vehicle rolling.
- Waterluvian 3y agoMaximum braking on an empty highway is still quite dangerous. The problem about “yeah well they should have left space” or “they should have responded perfectly to a car that’s suddenly braking” is that it’s not realistic to the real world. It’s not a least-surprise event.
- domysee 3y agoI'm not sure about the laws there, but in Austria for example it's also illegal to suddenly break without reason.
