I would like to see F1 in my home city, Munich. :D
This would be my layout:
Data
Lengh: 7,09 Km (4,40 mi)
Corners: 17
DRS 1: 1 Km
DRS 2: 1,3 Km
DRS 3: 500 m
Desciption
In my layout we would start and finish the lap on the "Ludwigstraße". Turn 1 would be a 90° right hander in front of the "Odeonsplatz". After turn 2 it goes into a fun section around the "Maximiliansplatz" (fast left turn [T4] -> 180° turn [T5], formed like parabolica -> fast left turn [T6]). After a fast right turn [T7] the second DRS zone starts which goes through a tunnel and down to the Isar. After another (tight) straight along the Isar and a left hander [T10] the circuit passes the Chinese tower and goes into the English garden. After a very fast corner [T12] the circuit leaves the English garden and goes into a chicane like in Monaco. After Turn 15 we're on the "Leopoldstraße", the 3rd and last DRS zone. This DRS zone is just 500m long, so it would be not possible to overtake but it would pull the rear car right into the back of the front car. So this zone is just to prepare for the next one. At the end you have to past the Siegestor at the left. If you pass it at the right you enter the pit.
