I came across this somewhere a month or so ago. Porsche has set up a live webcam aimed at the Porsche Customer Center with a stretch of the Porsche circuit behind it. A novelty, but pretty cool. I’ve already hit it a few times over the last day.
Refreshes every 5 minutes, so you can just hit refresh on the web page to see a new image. Check it out here: Porsche Leipzig facility.
This is now on my bookmarks and i check it out at least a couple times a day!
