As per Jacky Ickx, in the early days of Formula one, in one lap on the Nurburgring, drivers were jumping 17 times, 17!! The most challenging (deadly?) track in the world. Here is a very famous picture of Jackie Stewart and Graham Hill at the Nurburgring in 1966.
If you have raced on this track and experienced even a tiny jump, please share the experience and pictures below!
