Somehow, I suspect that autonomous vehicles with mediocre hardware/software (whatever is current really), might be as "impractical" (as in being directly hazardous, because of poor operational security) and as dangerous as having people in boxes go ballistic through pipes just to go as fast as one can that way.

If it was hacked that would be relatively easy to tell afterwards. Doubt it's the case here but if autonomous cars are networked they will likely be susceptible to hacking, which is a big problem imho. You can build unhackable systems in theory but it seems very hard to do in practice.

You could say it was 'hacked' - literally - if removing almost all of the LIDAR's is equal to 'hacking a system into defective pieces'  :-//

Maybe this is a case of someone "Muntzing" themselves to the lowest cost solution.  And going at least one step too far.

Everything is build down to a price. I don't necessarily see the problem with using LIDAR + stereo.

Stereo cameras in IR should be able to get a good depth picture near the car.

The car had an adequate set of sensors installed.  But various reports indicate one or more of the sensor systems was disabled.  No comments have been made on the processors, but there is always the possibility that some processing capacity was also disabled.

I agree, everything is built to a price.  But not everyone agrees on the minimum required performance, and there are certainly mistakes made on the route to whatever performance level a particular group is trying to achieve.

I will challenge this statement (but not too harshly).

Certainly, when it comes to mass production, this statement is true, but we are looking at research and development at this stage - and cost per unit considerations are not as important as establishing reliable solutions.

Once those reliable solutions are found, then the cost pressures come to the fore.

  That's a great point. If this can happen on what is arguably the best system available, regardless of the costs, then what happens when the bean counters are placed in control and the system is designed to be mass produced at the absolute minimum costs?   Every mass production car on the road is filled with countless examples of systems that were designed for minimum production cost at the expense of reliability, maintainability, repairability and performance. The radios, the carpet material, the seats, the ultra thin wiring, the poor quality connectors, plastic head lamp covers, cheap plastic body parts, the list goes on and on.

Cars (and every component in it) are built to a spec:  100,000 miles or 10 years.  Most cars beat that spec, if well taken care of you can double or even triple it.

There is no law against stupidity, there will always be stupid people.  Unfortunately this person paid the ultimate penalty.  If it was a normal vehicle, I'd say the driver was over-driving his/her headlights, according to what I saw in the video.  I know that when police use LIDR, shiny objects give the best signal, I suppose there was nothing reflective on the bicyclist.  I didn't say victim, not sure if that is the automobile or the bicycle.

I wonder how much a company would have to pay somebody to take a hit from an autonomous car?

It seems a good way to put a competitor out of business.  :popcorn:
