The huge Ford Excursion had an initial design flaw where it would do cool stuff like monster truck over smaller cars in a head on collision >During the development of the chassis, Ford learned that its initial design caused smaller vehicles (such as a Ford Taurus) to become severely overridden in a head-on collision. In the test, the tire of the Excursion drove up to the windshield of the Taurus (reducing the chance of survival for its driver). As a response, Ford modified the chassis to include an under-bumper "blocker beam"; the device was initially tested by the French transportation ministry in 1971. For the rear of the chassis, Ford chose to include a trailer hitch as standard equipment in production to reduce underriding in rear-end collisions by smaller vehicles. We've known huge vehicles are less safe for people other than the driver/passengers for at least 20 years. There's similar pushback on automatic driving cars...nobody wants to drive a car they know might make a choice to kill them to save others, and most people want their car to protect them at the expense of others.
