Fatal Tesla crash in Switzerland: a local report

Fatal Tesla crash in Switzerland: a local report by Paolo Attivissimo. An Italian version of this article is available here. A 48-year-old German driver died in the crash of his Tesla Model S on the A2/E35 highway in Canton Ticino, Switzerland, on May 10. Rescuers were unable to extract the driver and the car was completely destroyed by the fire that followed the accident. The crash has attracted considerable media attention locally and raised concerns about the safety of electric cars in general and Teslas in particular. I share those concerns on a very personal level, as I own an electric car (not a Tesla, but a much more modest Peugeot iOn). More importantly, I live close to the accident site and travel often on that same stretch of highway. The basic facts The accident occurred at this location on the A2/E35 highway near Monte Ceneri, on the northbound roadway (I’m using US English terms) around 3:30 pm local time. No other cars were involved. This is an annotated Google Maps screenshot of the area: north is up and the northbound roadway is the lower part of the highway, with northbound traffic traveling left to right. The two-way road below is the state road (strada cantonale), which is not involved. The crash site is just after a tunnel (bottom left in the screenshot above), where road work is currently being carried out and therefore northbound traffic is split: the left (overtaking) lane is diverted onto the southbound roadway, while the right lane stays on the northbound roadway. I took this video today, traveling exactly along the same route and lane used by the Tesla driver. I traveled at exactly 78 km/h (21.6 m/s), using cruise control to maintain speed. The local speed limit is 80 km/h (about 50 mph). The camera was fixed to my windscreen and was not operated by me. Road signs and barrier placement may have been changed slightly since the day of the accident. There are no large impact marks on the guardrails and there are few signs of skid marks. Quick timeline and distance references: 0:08 First road sign (on the right) warning of lane change ahead. 0:30 Second road sign (on the right) warning of lane change; 80 km/h (50 mph) speed limit overhead (it’s a reminder; speed limit is already 80 km/h before entering the tunnel). Notice how many drivers are disregarding the speed limit. 0:41 Twin speed limit signs at roadside (left and right). 0:51 Speed limit sign at tunnel exit. 0:57 Road divides with an S-turn. Notice yellow chevrons placed by police survey agents after the crash. Distance from tunnel exit is about 150 meters (6 seconds at 78 km/h). 1:01 Road straightens. 1:04 Fresh tarmac, diagonal white lines on the right lane and missing green markers on right guardrail suggest that this is where the car came to a stop and burned. This location is about 160 meters from where the road divides. 1:35 Diagonal burn mark on lane, possibly unrelated to accident, since it is 820 meters from tunnel exit (38 seconds at 78 km/h). The car may have been moved here. According to the initial police report published in local media (Tio.ch), the car overturned and was traveling south. However, photographs of the car on fire clearly show its B-pillar (the vertical part of the car body between the front and rear doors) standing upright and indicate that the location of the accident was a northbound lane. Other photographs, provided to me confidentially, show that the car clearly was not overturned in the initial stage of the fire and that its rear end was turned in the direction of travel. It would appear that the initial police report is incorrect regarding the overturning and the southbound travel. One eyewitness reported confidentially that the car was traveling well above the local speed limit, hit the lane divider and went into a spin, splitting at the front. Credit: Tio.ch/Rescue Media.

Currently it is not known whether the car’s driver assistance feature known as Autopilot was active or not. At first glance, the circumstances of the crash (road works with possibly confusing surface markings, excellent visibility and weather) would seem to suggest a crash induced by excessive reliance on Autopilot’s lane-following functions. However, when I drove through that very narrow S-curve with my car (much smaller than a Tesla Model S) at just below the speed limit I found that it required careful handling, as you can see in the video, even though the S-curve had been made less sharp after the accident, so perhaps the crash may have just been caused by the excessive speed at which the Tesla (a much wider car) was reportedly being driven. Therefore, it is unwise, at this point, to blame Autopilot or the driver. In view of the loss of life, I believe that the matter should be treated with caution and respect. It should be stressed that the driver is required to be vigilant at all times during Autopilot use, as stated repeatedly in the car’s manual and on the car’s display every time Autopilot is enabled. Why the raging fire? Media attention has focused on the unusual intensity of the fire. As reported by Ticinonews, the Fire Brigade of Bellinzona stated that “the violent impact of the lithium ion batteries probably caused a phenomenon known as thermal runaway, i.e., a rapid and unstoppable increase in temperature”. This is a well-known characteristic of all electric cars: for example, during the filming of The Grand Tour, ...
