According to the test standard developed by AAA, level 2 is equivalent to “talking while driving”, while level 5 is close to the level of difficult scientific experimentation that “completes distraction for the driver”.

Among the 10 models tested, AAA found that the Chevrolet Equinox's voice recognition function was the least likely to distract the driver and received a 2.4 rating; but the Mazda 6's in-car entertainment system was the opposite, with a score of 4.6, which was distracting the owner's attention. One of the most serious products. In addition, AAA also tested the impact of the smartphone voice assistant feature on driver attention. According to the researchers, the Google Now speech recognition feature that comes with Google’s native system scored the best, at 3.0. Apple Siri and Microsoft Cortana ranked second and third respectively, 3.4 and 3.8.

At the same time, experiments on "the degree of interference of the mobile phone voice recognition function to the driver" show that the attempt to use the voice command to send a text message while driving is most likely to cause the driver to be disturbed. Among them, Microsoft Cortana performed the worst, with a score of 4.5; Google Google Now and Apple Siri scored 3.3 and 3.7 respectively.

There are 15-27 seconds, it will still be in a state of mental dissociation and inattention. This distance can cover the length of about three standard football fields.

Beth Mosher, head of the AAA Chicago area, said in a statement, "It turns out that long periods of mental discomfort can seriously affect the driver's attention, and even you may not notice at all, the red light has turned green."
