Certain kinds of autonomous vehicles may not be safe, especially in an emergency situation, according to a new study published by the Lords Science and Technology Committee on Wednesday. With driverless technology, drivers may become over-reliant and complacent. However, with the development in the automotive technology over time, accidents by human error may be significantly reduced -- but they just might increase before they do. The committee also reported people may use driverless cars for shorter distances, as well, causing laziness and may prevent them from "getting exercise by walking." The UK Economic Opportunity split vehicles into levels from 0 to 5. Zero was fully controlled by an individual, and five was completely automated. According to peers on the committee, there was a "very dangerous" problem with vehicles reaching the middle of the scale, BBC News reported.

Certain types of driverless vehicles may not be safe, peers have warned. Over-reliance on technology could mean drivers react slowly to taking back control of a semi-autonomous vehicle in an emergency, they said. However, the Lords Science and Technology Committee noted that some technology could reduce accidents caused by human error. The Department for Transport said driverless cars "have the potential to transform the way we travel." Vehicles can be split into different levels of automation, according to industry body the Society of Motor Manufacturers and Traders (SMMT).
