As expected everyone jumped early at the whole terrorism angle, but so far nothing was made public about his motivations. He was known to the police, only for petty violence, but not to intelligence. Mentally ill people trying to go on a vehicular killing spree is not new, even if it never reached such heights. Is it terrorism without at least being emboldened by some political rhetoric or making a statement, let alone actual contacts with an organization providing logistics or some ideological cover ?
