When it comes to actions that make drivers in Pennsylvania inattentive and slow in their reaction times, one might think first of phone use, especially texting. Many also express concern over drivers who are impaired by marijuana. However, one piece of technology has been shown to be more dangerous than texting or driving high, and it’s the Apple CarPlay system.

CarPlay lets drivers use an iPhone as if it’s on an infotainment system. According to Apple, this can prevent distraction, but a study from the safety charity group IAM RoadSmart says otherwise. In fact, CarPlay’s touch and voice controls were shown to increase drivers’ reaction times by 57% and 36%, respectively. Contrast this with drivers being 35% and 21% slower in their reactions when texting or high on marijuana, respectively.

The study involved 40 motorists traveling a route in a simulator while being monitored for speed, their ability to hold their lane position and reaction times to various stimuli. Half used Apple CarPlay while half used its rival, the Android Auto. As a side note, the latter’s touch and voice controls caused drivers to react 53% and 30% more slowly.

Some drivers can act negligently with CarPlay, such as by programming destinations while on the road. Still, Apple can improve the system’s safety in numerous ways.

Drivers are responsible for staying attentive to the road. Therefore, they cannot blame technology for any motor vehicle crashes that they are involved in. Negligent drivers may become defendants in a personal injury claim. As for the victims, they may want to speak with a lawyer before moving forward. First, they need to see if they can file a third-party insurance claim since Pennsylvania is, after all, a no-fault state. A lawyer may hire accident investigators and other analysts to help with a valid claim.
