LOL - small screen texting for sure Floyd.
As I am sure you realized is what I meant to say was the dash lights are just as they would be if your headlights were not "ON"! LOL Pretty darn dark & only a few items are dimly readable. Forget about trying to change a radio station or adjust the ac or heat LOL at least on both my cars thats the case - only the US purchased Subaru has an idiot light all bright telling me the DRL's are on. After owning the car for several years it still causes me to look at it more frequently than I should admit, as I want to make sure its not a different warning light telling me of a problem.
Cant say I have noticed over the years an increase in people driving on highways at night without all their lights on. Also dont think I have seen it any more in Canada where DRL are the norm vs while driving in the US where they are not the norm. I see people without all their lights on far more frequently when driving in the city than I do on the highway -always have & suspect that is due to the increased street lighting
as people don't notice as fast that their dash is dim.
As far as whether or not DRL's work at reducing crashes here is a link to findings of various studies on the topic
. It appears most agree they do work.
