The DOT's new safety rules would add more crash tests, evaluate pedestrian safety in an accident, and check for the latest safety tech in vehicles. While still just a proposal, the updates could arrive for the 2019 model year.
Crash Test Dummies
It would be glib to say that safety equipment has had a huge influence on automobiles in the past 20 years. The result of cars being massively more safe than they were not long ago has made them bigger, heavier, more expensive, more challenging to develop, harder to fix and harder for emergency responders to deal with. That's just what it takes to try and keep people safe when they're wielding two-ton battle tanks in close quarters.
Anyone can be an ordinary dummy, whereas being a good crash-test dummy takes work. A few things you probably didn't know: the official name for a crash-test dummy is "anthropomorphic test device" (ATD), General Motors "has a long history" designing ATDs, and the process is so specialized that there's even a Rear Impact Dummy Task Group.
