"I don't see draconian measures being placed on drivers or cars."
There is about $1000 in airbags, crash sensors, and automatic seatbelt tensioners and considerable expense to using high-strength steel to allow lowering the weight of crumple zone structures and increased A-pillar (the front roof supports) to protect from roll-over crushing of the passenger compartment. This is in otherwise inexpensive vehicles traveling at generally low speeds on paths that are made with significant mitigations to protect errant drivers.
When seatbelts were first a required in passenger vehicles, not to wear them, just to have them, a considerable number of Americans demanded they would rather be thrown clear of a crash than risk being trapped by the seatbelt in a flaming wreck. Now cars nag and nag and nag for not latching the seatbelt, so much that\ the car will complain if one puts a bag of groceries on the passenger seat because there is a weight sensor that can't tell the difference between Sunday dinner and a 5 year old.
