Autobahn Polizei

I got this achievement while doing the case called "Toxic Waste". You jump from boat to boat on the ramps in the water and it popped on my first jump. This happens late in the game.

I have not found any other places or times in the game to get this. If you find one, message me and I will put it in.

Thanks to xSHADOWxWRAITHx for the following:
I also got it in the Tycoon mission. But I think you can get it at anytime as long as you can find your way to the Rhine River and drive into it
