Special Wave: When you see another LC500 on the road hit your Emergency Flashers for '3 seconds' to say hello.

 

The Lexus Fuel Cell concept car (LF-FC) presents a feature that allows one driver to to send a visual "You first" to a second driver who responds "Thank you" or something like that.
It looks like the letters appear on the street pavement, but perhaps it's more than that. I'd like the car's 'Remote Park' feature.
They have a video at the 'Future' section.

Enjoy the video. I like the way you think.

 

Cool video
