The posted image suggests the Honda was thrown more or less 90 degrees out from the collision point, while the Model S skidded right, then left, and ended up in the guard rail.
This fits with the Honda being a significantly lighter vehicle, and it's fairly easy to se it must have been a very violent impact. The Honda seems to have gone from 50 mph (?) to 0 mph in no time at all while simultaneously rotating several times before coming to a rest. To do that damage the Model S must have been going quite fast. Also, there are no apparent skid marks before the point of collision from either vehicle, which suggests it happened quite suddenly.
Edit: Also, there is a gentle curve to the road, which suggests the Model S should have turned but went straight. This suggests the driver was distracted. Perhaps looking to the right at a Mercedes?
