Police get tough with Ariel Atom supercar

ANYONE with a taste for speed might fear the sight of flashing blue lights in their mirrors, but nothing could be more frightening than this! British supercar maker Ariel has created this police-specification version of its new Atom 3.5 in order to support the Avon and Somerset Constabulary’s Safer Rider campaign.
