El Reg reports

[January 23] a Tesla Model S slammed into a stationary firetruck at around 65mph on Interstate 405 in Culver City, California. The car was driven under the fire engine, although the driver was able to walk away from the crash uninjured and refused an offer of medical treatment.

The motorist claimed the Model S was driving with Autopilot enabled when it crammed itself under the truck. Autopilot is Tesla's super-cruise-control system. It's not a fully autonomous driving system.

[...] The fire truck was parked in the carshare lane of the road with its lights flashing. None of the fire crew were hurt, although Powell noted that if his team had been in their usual position at the back of the truck then there "probably would not have been a very good outcome."

Tesla will no doubt be going over the car's computer logs to determine exactly what happened, something the California Highway Patrol will also be interested in. If this was a case of the driver sticking on Autopilot, and forgetting their responsibility to watch the road ahead it wouldn't be the first time.

In 2016, a driver was killed after both he and the Tesla systems missed a lorry pulling across the highway. A subsequent investigation by the US National Transportation Safety Board found the driver was speeding and had been warned by the car six times to keep his hands on the wheel.

Tesla has since beefed up the alerts the car will give a driver if it feels they aren't paying full attention to the road. The safety board did note in its report that the introduction of Tesla's Autosteer software had cut collisions by 40 per cent.

    Seems pretty obvious to me, no one trained the "AI" to deal with an emergency vehicle stopped in the HOV (carpool/hybrid/EV) lane. Just another example of Tesla using its customers for beta testing, nothing to see here, move along please...

    Update from Wired -- https://www.wired.com/story/tesla-autopilot-why-crash-radar/ [wired.com]

    Why Tesla's Autopilot Can't See a Stopped Firetruck
    ...
    This surprisingly non-deadly debacle also raises a technical question: How is it possible that one of the most advanced driving systems on the planet doesn't see a freaking fire truck, dead ahead?

    Tesla didn't confirm the car was running Autopilot at the time of the crash, but its manual does warn that the system is ill-equipped to handle this exact sort of situation: “Traffic-Aware Cruise Control cannot detect all objects and may not brake/decelerate for stationary vehicles, especially in situations when you are driving over 50 mph (80 km/h) and a vehicle you are following moves out of your driving path and a stationary vehicle or object is in front of you instead.”

    Volvo's semi-autonomous system, Pilot Assist, has the same shortcoming. Say the car in front of the Volvo changes lanes or turns off the road, leaving nothing between the Volvo and a stopped car. "Pilot Assist will ignore the stationary vehicle and instead accelerate to the stored speed," Volvo's manual reads, meaning the cruise speed the driver punched in. "The driver must then intervene and apply the brakes.” In other words, your Volvo won't brake to avoid hitting a stopped car that suddenly appears up ahead. It might even accelerate towards it.

    The same is true for any car currently equipped with adaptive cruise control, or automated emergency braking. It sounds like a glaring flaw, the kind of horrible mistake engineers race to eliminate. Nope. These systems are designed to ignore static obstacles because otherwise, they couldn't work at all.

    Looks like parent had a point, even if made in a crude way.

    Wired story has more explanation on the design tradeoffs involved, and why Lidar is needed (because, unlike radar, it can distinguish between road furniture (signs, etc) and an actual obstacle.

      This answer is exactly what I was asking for! But with this knowledge it is beyond scary to use this killer feature. If the leading car leaves the lane, there must be a reason! Usually it's not a problem, but sometimes there is something ahead in the lane. In my experience it was rocks, wood, a large chair, a broken car, a police car, a car on a red light (very common) ... every driver watches for these things, as he may need to brake right away. However this "autopilot" acts opposite to what a driver would do.

      I was a passenger in one of these adaptive cruise control cars yesterday when both the car in front made and the car I was in made a turn and they very nearly collided. Basically the car ahead slowed to take the turn and so the car I was in automatically slowed to keep the distance, but when that car disappeared just around the corner the car I was in accelerated into the "clear" space and our driver had to brake very heavily to make the turn and then steer to avoid the slower car in front. It was a little bit scary.
