Motorway slip roads (autoroute) that have caught me out a few times over the years are the exit slips off French autoroutes by cities.
The exit by Lyon leaves at a nice 140kph, goes into a 400m tunnel and then in 50m comes to an inner city cross roads with zebra crossing
Similarly, the exit slip into Reims takes you off at a steady motorway lick and at the top of the ramp there is a STOP sign and T junction with juggernauts crossing left to right!!!!
