The Guardian has this to say:
For the first part of the standoff, the Audi first smashed into the BMW and the parked Tesla, trying and failing to ram through. Seeing this, Blake sprinted away from the Audi, round first the side and then the back of the parked van, round the back of his car, and took a position protected by the side of the police BMW. He aimed his Sig Sauer MCX 5.56 rifle. For those seconds he was repositioning himself, he could not see what was playing out, but said he heard revving of the engines, tyre screeches and the Audi moving at “great” speed. It was no more than 12mph, the prosecution said.
Blake claimed officers were in danger of being run over or dragged under the Audi, but he could not point out in extensive video footage which officers’ lives he feared for.
How much damage can a vehicle cause at that speed?
