Actually, in almost all U.S. jurisdictions, inside mirrors are not required in pickup trucks (and not even passenger cars in some states), in that trucks are considered cargo vehicles and consequently it is assumed they will often have payloads that obstruct the inside mirror anyway.

re: mobile macs

Has anyone done this with an in-dash touchscreen unit? That’s what I want. I have an Explorer with the 4″ high stereo slot and would love to have that filled with an nice mac’d touchscreen.

An interesting sidebar about vehicle requirements: when I lived in Indiana 10 years ago I discovered seatbelt use was NOT required in pickup trucks. Seems the farmers have a strong enough voice there they got an exemption when the law was passed. Their position was that their farms are so huge in the midwest they often have to use public roads to travel between the different sections, and didn’t want to have to worry about it everytime they went to check the corn.
