> Consider another problem the vehicle already solves. The AV wisely yields to those running a red light, even though the AV has the right of way. If it didn't, but was instead frequently t-boned... Google could technically still say its vehicle "never caused an accident," right? It'd never be at fault for these, but the AVs are still designed to avoid them anyway. Is this inconsistent with a choice not to avoid rear…

DO hold the brake if you are about to be rear ended. It results in less acceleration, and you are less likely to be projected into an obstacle.

The kind of things I wish driving school could teach you. I don't know how, a set of busted cars on a driving loop with mild collision so you'd know what it feels and how to react. Kind like wet roads and collision avoidance classes.

Where in Europe? They certainly aren't here in Portugal nor in Spain, and I don't remember seeing them in Belgium, which I've visited recently. As for the legality, I wouldn't be so sure. Owning them is certainly legal, but filming the public street indiscriminately is usually considered against the Data Protection Directive, and I don't see why would dashcams be excluded.

Across Europe. OK I guess 'ubiquitous' might be an overstatement, but I regularly see cars with dash cams in Belgium, The Netherlands, France and Germany, which is where I have driven the last few years. I can't find any Europe-wide actual sales data, but I don't see why there would be huge differences in other countries. Also, they're readily on sale in e.g. Spain, Portugal and Hungary (just 3 countries I checked).…

I rarely see them, but I was told that stores do sell a few dashcam kits. I wish it was a standard practice, I couldn't care less about privacy, people are far too crazy on the roads, even on parking lots (I'd even buy 4 cams to cover all sides).

So... does anybody know what truck manufacturers are doing? As far I can tell it will take at least 20 years before AV can drop steering wheel and deal with scenarios like police officer routing traffic around accident site. On the other hand even current Google tech should allow for soft* road trains made from 2-4 trucks and only one (active) driver. Also new hardware price would have smaller impact on already expensive vehicles.

*without physical connection like in Australian ones

I'm fascinated by the accidents. The AV is stopped at a light. Someone rear-ends it. Minimal damage. Probably similar accidents are occurring every minute between human drivers, going unreported as the rule. AVs might one day even avoid this "victimization," if these events keep following a predictable pattern. AVs could exaggerate the gap, leave a precisely calibrated amount of extra space. When anticipating a rear…

The pragmatic thing to do legally is to license it before it is widely deployed and then hold it to whatever standard you established at that time.

That doesn't rule out making the standard more stringent over time, but determining what events the AI gets blamed for probably doesn't need to be a huge gray area.

I'm thinking the same-thing but they could even take this data out of the self driving car, apply it to a normal car and even in that case it would be a huge change that could be incredibly beneficial!

Some normal cars already have systems like this.

Which ones? Not saying I doubt you just generally interested :)

They might not be illegal here in Germany, but dash cam videos are regularly thrown out as evidence by courts. (And that's quite surprising, the bar is very high for that to happen in Germany. No fruit of the poisonous tree here.)

Daimler have a truck https://news.ycombinator.com/item?id=9555295 I'm not sure about the police routing around an accident thing. Google's cars can already recognise cyclists hand signals.

Your vehicle will accelerate less (fewer Gs) if your brakes are on.

The energy is still going to have to go somewhere. Some of it will go into the crumple zones, the rest will go into burning rubber and throwing passengers against their restraints. The question is whether a person is better able to withstand being pushed from the back with rapid acceleration, or absorbing the energy of a collision. I do not have an answer, but I'm very interested where I could find one. You mention w…

Yes, that is what the crumple zones are for!

Not sure what you mean by this: > pushed from the back with rapid acceleration, or absorbing the energy of a collision. The occupants don't have to absorb the impact if the crumple zones take it!

I guess decent seats will do a lot to protect the occupants. A few years back I was a rear-seat-passenger in one of these https://upload.wikimedia.org/wikipedia/commons/5/50/Nissan_M... when it was rear-ended. Luckily our driver WAS on the brake and didn't go forward into the cars in front - unlike the car behind us and the car behind them and the car behind them! (I forget exactly how many cars were involved but it needn't have been as many).

No. Rapid acceleration from being rear-ended causes whiplash. Having brakes on reduces the initial acceleration.

In modern bucket seats the risk of whiplash injury is incredibly minimal. Your head doesn't have the distance to travel far enough to hurt your neck. On the other hand, standing on the brake will cause both vehicles more damage and cause the other car to decelerate more quickly, causing the occupants to experience more acceleration in a direction in which the restraints are less effective (getting pressed into seat-b…

If there is a car in front of you, not holding the brake is shifting energy at their expense!

Does blame change though if there are ways the AI can prevent this series of similar accidents, but they choose not to? [...] Is it inconsistent to expect the AV to avoid getting t-boned, but not expect it to avoid getting rear- ended? While I was in college I worked on some wheeled robots that played a competitive ball game. We wanted to avoid collisions between robots, and to win the game. One of the things we foun…

So, human drivers will be faster and die more often than AV passengers. I choose slower and safer.
