Earlier quoted context omitted.
Do like in Canada: all cars must have their headlights on when driving (the lights automatically turn on). edit: also, I feel like if we add new light signals for acceleration, for example, it would be nice to add that to all cars.
Those are daytime running lights. I wish headlights were mandatory, that would eliminate people driving in rainy twilight without lights on.
An always lit in vehicle display and DRLs that are just always on headlights makes people forget to turn their lights on when it's dark. This isn't a problem for them since they have their headlights on but drivers behind them don't see them from a distance at night because their tail lights are not lit up. This is particularly dangerous in traffic where everyone else has their lights on.
Making DRLs mandatory is tripping over a quarter to pick up a penny because it enables this behavior.
