Doug,

I once saw a bumper sticker in Boston that said, "Don't get mad, just drive like we do".

>3. Not being at freeway speeds when merging onto the freeway, causing freeway drivers to either have to speed up or slow down, causing potential troubles.
>
>4. Not letting folks onto the road from driveways.

These, I believe, show a simple lack of education in basic physics, an objected moving at 40 MPH cannot merge with other objects moving at 55 MPH without a collision.
