Filmed in the Netherlands. Not sure how fast they're going, but i'm guessing at some points well over 90 mph (145km/h).

These shitforbrains of course have no idea what they're doing and give a crap about anybody's safety, swimming children, the huge waves they are causing etc.

Speedlimit in these canals is about 12mph (20km/h).

Police are also investigating this matter based on the video, but of course not too much will come of it.
