Manhole covers, rail road tracks, leaves, and lines painted on the road are all very slippery when wet. Also right after it starts to rain oils and such are still there making the road surface slippery. To lessen that risk keep your tires where the car tires run, there is less oil there.

I learned all I need to know about life by killing smart people and eating their brains.
