We were once caught in a heavy downpour on the highway and the taxi's wipers didn't work. The driver rubbed a cigarette on the windshield. The visibility was much better. Apparently tobacco juice prevents water drops from sticking the the windshield.
Ofcourse, this is a worst case scenario.
I found choice of clothing goes a long way in reducing driving stress. I don't carry anything in my pockets(wallets are a pain in the ***, literally) and wear full sleeved tees if its sunny. |
