Here is something more dangerous than speaking on the mobile phone on a freeway. Dreammaker Japan has developed TV screens to be placed on the sun visor at the driver's seat. To be used only when you are not driving, the screen is 9.2 inches wide and supports a resolution of 480 x 800 pixels. The unit is complete with a remote control.

In case you are still interested the Dreammaker visor screens will be available in Japan for 49,800 Yen ($ 430).
