#Question

Roll bars have been used in race cars since the 1950s saving 99% of the lives that would have otherwise been lost in accidents involving astronomical speeds and ferocity.

Why weren't they used in passenger vehicles, instead there are half belts, slow inflating bags, and gadgetry of relative inferiority?

Cost of mass-production?
Convenience?
Aesthetics?

The passenger compartment construction of MODERN CARS is like a roll cage. Not so my old 1965 IH Travelall. A hulking 2 ton overall weight station wagon type vehicle on a truck chassis. The whole top of the vehicle was held up by doorframes and glass and flattened if you actually managed to flip the thing.

Ps. Modern Cars are also designed to crumple the hood or have it pass over the windshield/vehicle on front end collisions to avoid decapitation of the passengers. Saab pioneered it.

Rolling alone is not what a roll cage protects from, despite of the common name. Most fatal crashes don't involve rolling, mostly cars hitting other cars at high speed differential or colliding with other hard objects, poles, walls, trees, rocks. Passive energy absorption came from race cars as well, as everything around the cage was expected to crash or be chopped off leaving the contents of the cage in tact. 6 point belts help keep the body inside the cage too.

You want submarining harnesses in stock passenger cars? Really?

I'll take the Harvester you take a Prius or a Smart and we can simulate a head on collision.

Race car rollbars are made of real steel alloys like what is used in bicycle frames of the past, not thin sheetmetal that tears like paper.

Windshields bearing structural loads didn't begin till the 90s when those wide gllue stripes were involved. BMW was still using unglued windshields till 91 (E30) but the pillars were tank like.

They still make convertibles without rollbars. !!
