Tesla Model S In Fatal Autopilot Crash Was Going 74 MPH In a 65 Zone, NTSB Says (latimes.com)

An anonymous reader quotes a report from Los Angeles Times: The Tesla car involved in a fatal crash in Florida this spring was in Autopilot mode and going about 10 miles faster than the speed limit, according to safety regulators, who also released a picture of the mangled vehicle. Earlier reports had stated the Tesla Model S struck a big rig while traveling on a divided highway in central Florida, and speculated that the Tesla Autopilot system had failed to intervene in time to prevent the collision. The National Transportation Safety Board released a preliminary report Tuesday that confirms some details of the May 7 collision, along with a photo that shows the car with its windshield flattened and most of its roof sheared off. The federal agency also included a photo of the big rig, circling an area on the right side of the tractor-trailer that showed the light damage the truck received from the collision. The 2015 Model S was moving at 74 mph, above the posted 65 mph speed limit, when it struck a 53-foot trailer being pulled by a Freightliner Cascadia truck. Tesla's semi-autonomous Autopilot driving feature was engaged, the report says.

    Apparently brakes were not applied. They believe it was a combination of the trailer being a solid light gray color that tended to visually blend in with the sky, coupled with the radar being designed to ignore large flat signs that cross above the road. So the trailer managed to be filtered out as an hazard and was ignored by the software.

    Forgot to mention. The car instructions say AutoPilot is not to be used where there are crossroads. In the Florida instance in question there were crossroads.

    No I get it - my point is how can you call this an "autopilot" if it doesn't even read road signs or figure out speed limits from GPS location or something. It's more of a "tries keep the car in your lane" device. I know it's just a detail, but lawyers have won lawsuits for less.

    Autopilot is exactly what it is ... Wikipedia: An autopilot is a system used to control the trajectory of a vehicle without constant 'hands-on' control by a human operator being required. Autopilots do not replace a human operator, but assist them in controlling the vehicle, allowing them to focus on broader aspects of operation, such as monitoring the trajectory, weather and systems.

    Cruise control is different from Auto Pilot.

    And despite being modded down for mentioning it - the whole concept behind this is the car is supposed to be controlling itself. Giving time for the pilot to go to the lavatory and stuff.

    At least that's the perception people getting killed by it think it is.

    That does explain the nasty looks I get because I stick to the posted speed limit.

    However, can we all agree that it is also incredible stupidity on Tesla's part to call this "Autopilot"?

    As a Tesla owner, I do not agree. Tesla makes it abundantly clear what the capabilities and limitations are. Nobody that is actually using it has been misled.

    I typically drive 10 mph over the posted speed limit, both on freeways and on roads. IMHO, the posted speed limit is for either A) the driver with dementia who shouldn't be driving anyway, or B) some government that needs the speeding fines to balance their budget.

    Go Los Angeles and there are some freeway offramps marked 25 MPH and, goddamit, they farking mean it oh holy shit will I make it. But as time goes on those honest speed limits get replaced with better intersections, but the speed limit stays the same.

    Freeway speed limits should be 80. Non freeway speeds should be a good 10 MPH over what they are already.

    Lucky you're not in Australia.. I have been booked (via hidden camera) for doing 64km/h in a 60km/h zone (39.8mph in a 37.2 zone).

    Police generally will pull you over if you're doing 10km/h over the limit (6.2 mph) as the fine doubles at that point.

    15km/h over (9.3mph) triples the fine.

    And I'm not just talking about police on traffic duty - any police car will pull you over if you're speeding.

    If you get caught doing 25km/h over (15.5mph) that's an immediate loss of license.

    Our highway / freeway limits (apart from some isolated stretches on interstate highways) are all 100km/h (62mph).

  8. Trailer under run bars would have saved life by nicolaiplum · · Score: 4, Informative

    Look at the way the trailer took the top of the car off while barely slowing it down. This shows how trailer under-run bars would have prevented this death. In Europe they are required, and we basically don't have this sort of side collision decapitation horror accident.
