Sorry but I have to disagree.
I drive my car for a living and in my job there is no other choice because I have to carry a whole lot of equipment at all times.
So I spend 3 hours behind the wheel about every day of the year.
Believe me: I know traffic and I have developped a sort of "third eye" to get through it easily.
Most professional drivers do.
What I see is that many people drive like total idiots but ... it does not help them at all to get through traffic and it is very dangerous.

I drive extremely defensive yet very smooth but never aggressive.
I allways have an eye out for all bikers aswell
