I can only speculate, but I would say this data doesn't disprove the causality of the other cohorts. Just because the results are absent in another region it doesn't mean those same conditions will yield the same results, although it's idea of something to try.

Owning a smartphone and using it while driving aren't the same thing. I think work culture differences my contribute more than mere smartphone ownership.

Fair enough, I also found the other comment re: the prevalence of manual transmission in Europe compelling.

Yeah, I share that same feeling.

However, where this starts to break down is highway miles. Shifting into overdrive and having no lights for miles, coupled with the always connected to work ethic might have different results.

I do think it ultimately comes down to culture and conditions on the road.

Re: work culture I have been ordered to be on conference calls while driving to the airport on a weekly basis. Never would do so otherwise as I hate talking on the phone period let alone while driving in traffic. Feels bad man.
