The sentence from the source which best supports this reason is the following one:
- Some studies suggest that texting doubles a driver’s response time to roadway hazards.
That is the best reason since it is not only about making drivers distracted, as in number but it is actually about a change in the number of seconds it will take a driver to react when facing a roadway hazard (it will take longer).
When it comes to driving, a few seconds make the whole difference (actually, the difference between life and death) and if texting impairs drivers it should be banned indeed.
