科技輔助增加安全和事故數增加 二者不見得有直接關聯性 ADAS至少在理論上是可以增加安全性的 這個美國IIHS是有做過研究 Real-world benefits of crash avoidance technologies HLDI and IIHS study the effects of crash avoidance features by comparing rates of police-reported crashes and insurance claims for vehicles with and without the technologies. (May 2018)
Forward collision warning 27% Front-to-rear crashes 20% Front-to-rear crashes with injuries 9% Claim rates for damage to other vehicles 16% Claim rates for injuries to people in other vehicles
Forward collision warning plus autobrake 50% Front-to-rear crashes 56% Front-to-rear crashes with injuries 13% Claim rates for damage to other vehicles 23% Claim rates for injuries to people in other vehicles
Lane departure warning 11% Single-vehicle, sideswipe and head-on crashes 21% Injury crashes of the same types
Blind spot detection 14% Lane-change crashes 23% Lane-change crashes with injuries 7% Claim rates for damage to other vehicles 8% Claim rates for injuries to people in other vehicles
Rear automatic braking 62% Backing crashes 12% Claim rates for damage to the insured vehicle 30% Claim rates for damage to other vehicles
Rearview cameras 17% Backing crashes
Rear cross-traffic alert 22% Backing crashes
Added costs Lower crash rates are a clear benefit of these technologies, but some features can lead to higher repair costs in the crashes that do happen. That’s because sensors and other components are often located on the vehicle’s exterior. For example, in the case of forward collision warning without autobrake, the average payment per claim for damage to the insured vehicle goes up $109 for vehicles equipped with the feature.
