My results:
30:25 -> Runner hits me during my chase. I was the suspect, and I tried to annoy Taj getting in that space between the walls. Runner was there stopped, and just when i was gonna pass through his left, he accelerates and hits me. Nothing special, but of course not allowed.
33:30 -> Runner follows the chase. Same place. I went into the same space, and Runner, instead of driving away (there was no danger of hitting us), he stops in the middle of the road, close to the chase. That makes me then avoid him when I run away from Taj.
37:00 -> There's when Runner crash Taj. Taj was going from the right to get on the road again, and Runner was coming. But the fact is that Runner had WAY enough time to see Taj and do something to avoid him, like going into the grass, to the left, etc. Instead of that, he continued straight, he didn't even tried to avoid Taj. Then Taj spectated him.
My opinion: Taj is innocent. Runner is guilty.
Edit: Runner, don't tell me that you didn't have enough time to avoid him. Since Taj is seen on the screen till you crash him, 4-5 seconds passed. That's enough time to notice him, see where you could go to avoid him, and avoid him succesfully.
