After seeing the ad on TV recently showing the collision between a 98 Corolla and the 2015 model, which is used to demonstrate the increased safety of modern cars, I started to think about how cars are rated as years progress under ANCAP. The highest rating is five stars, but cars have been getting 5 stars as the top rating for years. Even my 2015 Captiva gets 5 stars, but I bet it wouldn't rate that highly if it was assessed against current standards and this is why I believe the current system is flawed. IMO, the rating system should extend beyond 5, with no upper limit. A 2015 model with 5 stars sounds OK, but if, for example, a 2019 model attained 8 stars, that would put things into perspective and enable buyers to see for themselves how safe a two or three year old car, that once rated highly, really compares to a new car with improved safety. The current system can be very misleading and older, 5 star cars could in fact be much less safe by comparison than the ratings suggest. Comments?
