Yeah, i don't really know how to force a crash. All i did was hold w in the chase for most of the time. I had about 29% fuel left in my car so i was prepared to eventually get out and fight (and die like i almost always do) but then samp crashed. Oh, there was actually another chase where i had robbed a bank and kiru was about to get me, but then his samp crashed. That may be why he is a little annoyed/mad.
