Three top luxury cars have been named in a report slamming the cars with the worse visibility. It seems from the report, which has been compiled by Which? Car, that owning a car designed for rear luxury dramatically reduces the visibility. The Porsche Panamera, Volkswagen Phaeton and the BMW 5-SEries Gran Turismo were all mentioned as scoring around 40%, which calculated on a number of criteria such as interior mirror visibility, exterior mirror visibility, windscreen wiper clearance, pillar thickness and all-round view. As cars are made safer and stronger, this is reported to play a major part in reducing visibility as car door pillars, for example, are made chunkier.
