Perhaps "any speed" was exaggerated but I wouldn't call the thing click bait when it legitimately called out manufacturing practices and reluctance to put resources into safety which thereby resulted in trivially preventable deaths.

The greater awareness of safety factors brought to light by the book resulted in a culture of safety around automobiles & consumer buying practices that made safety features primary marketing & selling points.

That's all a pretty high bar to reach when using "unsafe at any speed" in the context of address spaces.

So long as you kept the tires inflated. It had a strange motorcycle-like difference between rear and front tires. I don't know if you could feel the handling get bad if that wasn't preserved or if it would surprise you in extreme situations.
