overall US motor vehicle fatality data, showing that SUVs and pickups generally had a higher fatality rate than cars of the same manufacturer. According to Consumer Reports, as of 2009, SUV rollover safety had improved to the extent that on average there were slightly fewer driver fatalities per million vehicles, due to rollovers, in SUVs as opposed to cars. By 2011 the IIHS reported that "drivers of today's SUVs are among the least likely to die in a crash". Braking problems The cars with larger and heavy size like SUV require massive amounts of braking power so the reaction of an SUV to sudden braking can be very different from that of a normal car variant which drivers are more accustomed to. Construction Heavier-duty SUVs are typically designed with a truck-style chassis with separate body, while lighter-duty (including cross-over) models are more similar to cars, which are typically built with a unitary construction (in which the body actually forms the structure). Originally designed and built to be work vehicles using a truck chassis, SUVs were not comprehensively redesigned to be safely used as passenger vehicles. The British television programme Fifth Gear staged a crash between a first generation (1989–98) Land Rover Discovery with a separate chassis and body, and a modern Renault Espace IV with monocoque (unit) design. The older SUV offered less protection for occupants than the modern multi-purpose vehicle with unitary construction. In some SUV fatalities involving truck-based construction, lawsuits against the automakers "were settled quietly and confidentially, without any public scrutiny of the results—or the underlying problems with SUV design", thus hiding the danger of vehicles such as the Ford Bronco and Explorer compared to regular passenger cars. Risk to other road users Because of greater height and weight and rigid frames, it is contended by Malcolm Gladwell, writing in The New Yorker magazine, that SUVs can affect traffic safety. This height and weight, while potentially giving an advantage to occupants of the vehicle, may pose a risk to drivers of smaller vehicles in multi-vehicle accidents, particularly side impacts. The initial tests of the Ford Excursion were "horrifying" for its ability to vault over the hood of a Ford Taurus. The big SUV was modified to include a type of blocker bar suggested by the French transportation ministry in 1971, a kind of under-vehicle roll bar designed to keep the large Ford Excursion from rolling over cars
