It appears to me he was speeding. But we must also remember that because the size of the bike is so small, it appears to be going much faster than it was. And it's much more difficult to judge it's speed as well.
The reason why I said it appears he was speeding because he passed one or two vehicles like they were standing still. But again, the cars could have been going 10mph.
Crash investigators will be able to determine exactly how fast, since they have the video. Just comes down to basic math, time and distance.
As mentioned earlier, does not appear like the cager did an illegal u-turn, just simply pulled out of a driveway. Did anyone notice the guy standing next the building when all this happened? He witnessed the entire thing and he just stood there like nothing ever happened. WTF?
