Great article. This should get some pots stirring. I've been saying for years that using a phone while driving, EVEN HANDS FREE, is at least equal to driving drunk or stoned. Now there's a claim it could be worse!? Yikes. Apply grains of salt as required.

IAM RoadSmart Infotainment Research 2020
IAM RoadSmart research shows that Infotainment systems have a significant adverse effect on drivers' reaction times in new research report.

Key research findings:
1. Controlling the vehicle’s position in the lane and keeping a consistent speed and headway to the vehicle in front suffered significantly when interacting with either Android Auto or Apple CarPlay, particularly when using touch control
2. Participants failed to react as often to a stimulus on the road ahead when engaging with either Android Auto or Apple CarPlay – with reaction times being more than 50 per cent slower
3. Reaction time to a stimulus on the road ahead was higher when selecting music through Spotify while using Android Auto and Apple CarPlay
4. The impact on reaction time when using touch control (rather than voice control) was worse than texting while driving
5. Use of either system via touch control caused drivers to take their eyes off the road for longer than NHTSA (National Highway Traffic Safety Administration) recommended guidelines
6. Participants underestimated by as much as 5 seconds the time they thought they spent looking away from the road when engaging with Android Auto and Apple CarPlay via touch control.
