so that people can see you better since, you have to remember, every other person on the roads with you is a terrible driver.
they were mandated in the US in...02? or something. maybe not required like seatbelts but some insurance companies give you a lower rate...like having airbags, an alarm, etc.
Oh, i have no idea they were mandated...so every car made after 02 or whenever has DRLs?
I don't see how it could help other people see you. I mean, it's a car, it's hrd to miss in the daylight. But you're right, every other driver is a terrible one. But why don't we just drive with our high beams on? That would make it VERY easy to see a person driving. lol.
