The accident was most possibly caused by several factors:
1. The road was covered with thick slush walls between tracks.
2. The weather was windy (6 to 11 m/s), moist (rel. humidity 100%) and temperature was just around the freezing point (0 degrees Celsius).
3. The accident happened in the place, where the road gets out of forest and was open to the gusty crosswinds.
4. The driver was 50 year old woman, who might still had only small winter driving experience. The information about experience is wild guess, because several officials and social workers participating in the Electric Mobility program, had less than average driving experience.
The car was the same color as most of the cars in the other pics. The bluish glint is caused by the strobes of the rescue/police/ambulance car.
Here is another pic of the car, this time without the strobe glint:

Video of another winter accident with iMiev, this time near to Tallinn Airport:

This time the rental iMiev, coming from the city centre, tried to turn left towards the airport and collided with the Peugeot, that was moving towards the centre.
Traffic light for iMiev changed into red, but the driver hoped to finish maneuver before the Peugeot, who was rather slowly approaching to the intersection, but accelerated as his lights changed green.
