> Is that because their vision fails to provide the information necessary to drive safely?
In certain conditions, yes. Humans drive terribly in dark and low light, something lidar excels in.
Still, millions of humans drive every night and only a miniscule percentage cause any accidents. So maybe we are not so bad at this.
According to NHTSA, about half of all fatal crashes occur at night, even though only 25% of driving happens at nighttime. So yes, we are pretty bad at this.
