I think there's two vans, Raggy. One goes past him, the other follows him after he swerves & accelerates. But yes, we agree that at the moment it looks more likely not a terrorist attack - the latest version of the BBC story says BBC home affairs correspondent Daniel Sandford said sources told him the suspect is from the Birmingham area and was not known to MI5 or the counter terrorism network, but was known to police (my bolding). He is also said to "not be co-operating with counter-terrorism police".
