It won't see the light of day in that form. Too much liability risk. I've been overtaken while stopped at a zebra on at least 2 occasions.

From the link. "When the car approaches a pedestrian crossing, it can warn those waiting to cross that it has ‘spotted’ them. The grille is then able to display green arrows that show it’s safe for them to cross" Rule 195 UK highway code. "do not wave, flash your lights or use your horn to invite pedestrians across; this could be dangerous if another vehicle is approaching" Looking at the image of the Skoda grille with the green arrow ok to cross, it looks as if it is set up for driving on the right - ie pedestrian is crossing right to left as seen by the driver in front of the car, so probably not intended for the UK.

The number plate on the front of the cars is from the Czech Republic...although don't think this a real thing that they are thinking of doing - just showing a 'what if' kind of product.
