OK, sad git time here. I couldn't resist trying to work out what speed the car is doing in Rendezvous and now that Google Earth and Autoroute exist it's a piece of cake.
The opening scenes show the car leaving the Peripherique and Entering the Avenue Foch and then driving down the Champs Elysee. ICBA to work out timings for other sections, but I get the following:
48 52 17.91 N 2 16 32.12 E Avenue Foch48 52 24.58 N 2 17 45.24 E Champs Elysee (0.853 miles 38s 81 mph)
48 51 57.36 N 2 19 10.70 E Place de la Concorde (1.23 miles 60s 73.8 mph)So it's fast for a city centre, but not that fast and those are bloody great big wide absolutely straight boulevards.
Runs a lot of red lights though.
