What are some mistakes you observe drivers doing on a regular basis?
The ones I see go from ordinary to super freakin crazy, such as going the wrong way on an off or on ramp.
Not using turn signals.
Stopping full in their lane, on a four lane divided highway to clean the ice off their wipers, no one else was stopped just them.
And forget about texting I have seen people working on their computers while driving down the road.
What have you seen?
