Thanks for reminding me. I knew I'd seen adaptive headlights
recently but couldn't think where - it was a DS on the BBC's
Top Gear program last week. They did have some good things
to say about it and mentioned some of Citroen's innovations

"New presenter Richard Hammond's vote is for the Citroen
DS (pictured bottom left), which was launched in 1955. Light
years ahead of its time, the DS changed the direction of car
design when it was unveiled, and 12,000 orders were placed
almost immediately"

I don't think they mentioned that it, I believe, can run on only 3
wheels because of the smart suspension
