How do I remove the white road marking paint from car?

[X5only]

The front and rear wheel wells and rear bumper have the bloody white road marking paint splashed all over. Does anyone have any idea how to remove the road marking paint without damaging the car's paint? The road coontractors didn't let them dry before allowing traffic to pass over the freshly painted markings. I feel like sending them the bill of whatever I spend and my time! May be I should write to the city council if this turns out to be a complicated removal process.
