Infiniti has just announced that its new M35h will be the world's first hybrid with a standard audible pedestrian warning system to alert pedestrians when the car is running silently on EV mode. Infiniti calls the system VSP, or 'Approaching vehicle sound for pedestrians'.

Rinspeed Dock + Go: the details Frank Rinderknecht calls the Smart trailer 'a backpack on wheels'.
