The 2010 Bentley Continental Flying Spur is exceptionally rare and expensive, and as such, it hasn't been crash-tested by NHTSA (National Highway Traffic Safety Administration) or the IIHS (Insurance Institute for Highway Safety).
A full complement of airbags and standard traction and stability control systems are included. The Continental includes active rear headrests that can reduce the likelihood of whiplash, but it's not all serious stuff. Edmunds noted that the Speed version made "Sport" for the traction control setting more fun; it's now less intrusive.
Visibility from the driver's seat is compromised by the Flying Spur's large pillars. ConsumerGuide describes how "visibility is generally good all around, though thickish front pillars compromise [the] forward view to the corners."
