Bit of armchair CSI here.
It looks like the Fabia hit something first and just lightly rolled into the Tigra. Everything that follows is an opinion
-The front left is damaged, the opposite side to the Tigra.
-The rear left also looks damaged (or just a reflection, hard to tell 100%)
-From this angle it looks like it is the passenger airbag that has deployed but not the drivers, meaning the main force of the impact was on the front left (IIRC airbags only deploy on the area of impact)
-The gray railings between the Mercedes and the guy standing in the hoodie are completely bent up.
-Front left tire has popped, maybe due to hitting the kerb at speed.
-drawing a line from the front to back and beyond of the passenger side kind of confirms that it was on the kerb.
If the main impact was on the Tigra it should have been a much bigger mess than a small crease on the door to deploy an airbag.
Fabia mounts kerb, pops tire, hits railing, airbag deploys, Fabia swerves to the right causing the rear to swing out and catch the barrier, Fabia slowly rolls into the Tigra.
Reasons could be many.
I could also be very, very wrong. lol
CSI Wirral, ber dun dun ber dun dum dum der dum.
Looks like a 63 reg too, less than 6 months old, bet the driver is not too happy at all.
Anyone else want a go?
