maybe he thought the barrier would pull off to the side because he had siren and lights on.
What an idiot. The simple fact that he was driving that fast on crowded urban streets is stupid, even if he is responding to a call with his blues and tunes going.
At the speed he was driving there would have been no time for a pedestrian to get of the street even if they did hear the siren.
I hope he isn't hurt too bad, the public shouldn't have to pay his disability for the next 20 years.
