man i was on my motorbike from work

then suddenly the rain start to fall so heavly

the raindrop hit the helmet like bullet

That's good idea.

That's nightmare for all the riders....

sometimes can't see clear

if riding fast then is ok cos the rain goes away but riding not so fast rain drop stays on the visor longer

and the helmet steams up and then if you try to open the visor to breath the rain hits your face like a sharp knife

So....you stay under the bridge (if there is one) for a while?

no i was on motorway so got home really quick anyway but was soaked
