We've heard the marketing babble, and pondered the possibilities of a hands-free drive to work, but do those radar-based collision prevention technologies actually work? The British Motor Insurance Repair Research Centre Thatcham seems to think so. BMIRPCT took a long hard look at Volvo City Safety
, Mercedes Distronic Plus
and Honda CMBS, and decided the technologies will have a major impact on slow speed accidents -- which account for 75% of accidents as it is -- and should prevent more than 125,000 injuries a year in Britain alone, according to this research.
