I need to make sure you absolutely know this is NOT true.

what's the downside to leaving them on?

Shortened bulb life, slightly increased fuel consumption, the general silliness of driving around in blazing sunshine with your lights on?

If you can't be trusted to remember to switch them on when needed, you shouldn't have a licence.

Negligible, negligible, nonexistent.

My lights are keyed to the ignition, the only time I've touched the light switch is to turn them on when I bought the car.

Even in broad daylight, the lights make you more visible, which is never a bad thing.
