M1 Crash update "After the verdicts, it was revealed Masierak's professional driving licence had been revoked prior to the crash." Maybe AIM Logistics should have questions asked of them. |

M1 Crash update Have to say i'm a bit surprised at the sentencing. Yeah, Masierak was a frequent offender & unlicensed at the time of the crash and that alone would make him eligible for the sentence he received IMHO, however usually such offenders only get a few months suspension & a fine (at least here anyway) & most of the imposed sentence was for culpability in "Death by Dangerous driving". But what if some other truck driver had a break down, or had stopped because of debris on the road? The crash was caused by the second truck's driver (Wagstaff) not paying attention & running in to the back of the other vehicles. Would a different stopped driver also be held accountable because they had to stop? Masierak got what he should have, just for being a frequent offender & unlicensed, however i'm surprised he got such a stiff penalty for being held culpable. But Wagstaff got off way too lightly (40 months) as he was the one most responsible for the accident IMHO- "...had between nine and 11 seconds to see the vehicles ahead." 5 seconds is a pretty long time, 10 seconds a very long time in order to react. He was "on a hands-free call for an hour at the time of impact and ... he did not brake before crashing into the minibus at 56mph." Grant Darwin NT |

However it raises questions. Who is liable in this case? Multiple lanes? It wasn't. But the woman with the bike trying to cross the street in the dark on a place that no car drivers are not expecting anyone... Whatever. Who came up with the idea to test self driving cars in a city environment? Wouldn't it be better to test them first on highways instead so they can fix "latency and computer algorithms problems" before testing the cars in a city? |

Have to agree with you. Unfortunately, here anyway, that is the biggest loophole regarding transport safety. Until that is plugged... |

Until that is plugged...Some of the questions need to be asked of the jury (but unlike America, they can't be asked in this country). The jury found Ryszard Masierak guilty of causing death by dangerous driving. They found David Wagstaff innocent of the same charge. We'll never know why. |

Multiple lanes? It wasn't. The article says this The video shows the vehicle travelling in the right-hand lane of a divided four-lane roadway. The vehicle’s headlights illuminate a woman directly in front of it who is crossing the SUV’s lane with her bike. The woman appears to be jaywalking as she is not in a crosswalk. And the video they have shows multiple lanes. But the woman with the bike trying to cross the street in the dark on a place that no car drivers are not expecting anyone... They have been testing them for years on remote roads. They were running on a major 4 lane divided road in a City, then they'll test them on undivided roads, low traffic single lane each way roads then high traffic ones, etc, etc. It's called testing. And have you actually watched the video? Even if the person in the driving seat was driving, they would have had to have done some laws of physics defying driving not to hit that person at all as the period of time they were visible- keep in mind the video on that web site is in slow motion, not real time- was bugger all. Looking at the video in real time- even knowing what to expect & where- I count less than 2 seconds from the time I can see the person to impact. That is less than the average person's reaction time, let alone the distance required to stop. The simple fact is that if this hadn't been a driverless car, it would have just been yet another pedestrian hit & killed crossing the road. Yes- Uber needs to determine why the car didn't detect the pedestrian (or why it did detect them, and not respond). However even if the car did work the way people expect them too, there's a good chance the pedestrian would still have been hit as braking distance is greater than reaction distance. Even with 0 reaction time & distance, instead of being hit and killed by the right hand side of the car, they would have been hit & possibly killed or seriously injured by the left hand side of the car. Given 0 reaction time isn't possible, impact was always going to occur. Grant Darwin NT |

That's it in a nutshell. Too many drivers ignore time. Reaction time+Braking distance(takes time to actually stop)= injury or death if impact within that time span. |

They were running on a major 4 lane divided road in a City, then they'll test them on undivided roads, low traffic single lane each way roads then high traffic ones, etc, etc. It's called testing. Lets face it. How many real incidents and possible incidents can actually have been tested for years as you say? Of course simulated tests have been done but now it's real! Sorry, we humans are not ready yet to embrace the new technology yet. Do some extensive tests on the highways first then rebuild the city infrastructures to suit the cars and then test self driving cars in the city. It will take many years but it's needed to be done if we want transportation safety. |

Not a promising beginning. Teen fails her driving exam by crashing into test centre before leaving carpark. Grant Darwin NT |

Piece in NYT Uber’s Self-Driving Cars Were Struggling Before Arizona Crash The cars were having trouble driving through construction zones and next to tall vehicles, like big rigs. And Uber’s human drivers had to intervene far more frequently than the drivers of competing autonomous car projects. Think Uber need to go back to driving on test tracks before trying anymore live driving on public roads. |

Think Uber need to go back to driving on test tracks before trying anymore live driving on public roads. And Volvo with their XC90 model! Just one year ago, a self-driving Volvo XC90 collided in Arizona. The car belonged to the taxi company Ubers test cars in Tempe, Arizona. Uber interrupted the test runs for some time, but when the police found that the counterparty caused the accident, the trial runs continued. |

Yes, and also from big cars like SUV's that sit so high on the road, their beams hit my line of sight more directly.  The mind is a weird and mysterious place

Anyone experienced this issue?My new car has LED headlamps, and when I'm parking up in an enclosed space, I can see how sharp the upper beam edge is - how narrow the angle between 'dip' and full intensity. When I meet drivers of other similarly-equipped cars on the road, there's no problem - in fact, I prefer the way that the light comes from a wider area, not the pin-prick of (particularly) a halogen bulb. But if the road is undulating, so the lights sometimes aim slightly above the level they're adjusted for, there can be a problem. |

Anyone experienced this issue? Yep. Not so much that the lights are brighter, just that there seem to be more poorly aligned lights than in the past. Grant Darwin NT |

Anyone experienced this issue? Also seems to be an issue that the sources are more pinpoint. After all the size of a LED junction is microscopic compared to a tungsten filament. So there is no penumbra. |

Anyone experienced this issue? The original lenses was probably perfect, but then the 'car designer(s)' insist on a clear plastic cover that follows the shape of the car. |

A few weeks ago I had one of the Euroblob pool cars from work and was concerned about the number of times I was flashed by on-comings cars. So I did a quick "garage door"check which showed both headlamps were pointing up and to the right rather than down tp the left. On a car with less than 1000 miles onthe clock this can only be down to manufacturing issues and lack of PDI checks. The brush off from the hire company resulted in a customer complaint.
