You say traffic hazard, Domino's says "branding opportunity."
Domino's in the Netherlands appears to be experimenting with a scooter that emits the utterances of a man saying "Domino's!" and "pizza!" in between revving noises. It's a solution of sorts to the problem of soundless electric vehicles, which provide no aural warning to pedestrians or other drivers and are a special hazard to the sight-impaired. The auto industry has responded with electric vehicle warning sounds that in some cases are designed by Hollywood special effects wizards.
