Does ur car has side mriior heater? if hav, then u must on it ,
it does help.
If not ..nuthimg much u can do except b very alert n careful, if u
think u really scared to drive, then slowly find road shoulder n
stop,rememeber ur hazard lights ok!?
wht i did last time was apply rain-X on my side windows n mirrors,
n rearwindscreen,,it helps quite abit as rain water jus flow
down.
but do NOt apply on ur front windscreen as it will spoil ur
wiper.
other than that..its a tricky rainy situation..so kick down, drive
safely.
