<human>: Can you condense the text into a few key points?

I had a car accident on friday, other party involved was speeding and hit me. but because he denies it it seems like I was wrong because he was supposed to go first under normal circumstances. ( give way road markings ) 

but because it was clear when I checked it I drove on, and when I was almost past the intersection he slammed me in the side near the back seat. and caused me to slide across the road for 2-3 meters hit a street light and then bounce back a meter. both doors completely jammed so i had to climb out the window...

can I somehow get an investigation going about this to see how fast he had to be driving to get this much force in the collision?
because the damage on my car would suggest that he was driving way faster than the legal limit there. ( which is 50 km/h )

also another reason why i think he was going way faster than admitted is because he could never have reached the intersection from such a distance as where i could not even see him yet

(pictures of the damage:  ) as you can see with the damage, I am lucky to be alive and unharmed right now... 1ft further forward and it could have been my end...

help would be appeciated on this :)
<bot>: we suspect other party involved of speeding when he hit me but I can't prove it without an investigation into the damage, how can i get such an investigation ? if at all possible.
