How does one signal a fellow truck it is OK to change back to the right in the dark? Your headlights are on, do you turn them on to off to on, or do you flash the highbeams? So only the lights will "spook" livestock and not the sound of the machine driving up on them? DRLs are just a feature, nothing more. Most of the reasons people hate DRLs they mentally manufactured "just cause". What about all the other systems in a modern automobile that are not controlled by the driver? How can we let that go on? As I said in a previous post, DRLs are not a huge factor for me. If the vehicle has them OK, if it does not, OK. Automatic headlamp OTOH are a must for a vehicle I buy.
