“According to EuroNCAP crash testing, the current model Fit (known as the Jazz in Europe) is vastly safer than most larger cars of even ten years ago”
Safe crashing into a wall or another vehicle that isn’t higher than the beltline. I agree the airbag and crumple zone technology is amazing for those type of impacts.
BUT it does nothing to prevent you from being run over or decapitated by a much higher vehicle. Roof pillars are nothing versus something like a dumptruck and they can never be designed to handle that much mass.
A heavier vehicle with the same safety technology will always be safer than a lighter one. It’s simple physics that a heavier vehicle will reduce the forces on the occupants when all other things in the accident are equal.
