driving in a downpour

[falken]

While I make it a point to tell anyone who I can influence to not turn on their hazard lights under heavy downpour, I've also personally experienced rain that's so hard that rear tail lights are hard to see. Hazard lights are brighter than tail lights (about as bright as brake lights) so it really does increase visibility. What can you internet experts say about that?

You can't expect people to add RFLs so they make do with what they have. A lot of people never ever change anything in their cars, save for necessary maintenance.

It's still not advisable.
