People biking the wrong way on bike paths

I need to vent. Maybe it's just that I started noticing it more lately, but I have a feeling there's an influx of absolute idiots biking the wrong way on the bike lanes and it bugs the fuck out of me.

These people are just too lazy to cross the road when they needed to or dont't know that it's a one way lane, but I can't imagine it's the latter.

Example: on busy, one way, small bike lanes (Overtoom and other streets, you name it) where people are overtaking eachother constantly, people are biking against the direction of traffic.

It's stupid and dangerous. Sometimes I make eye contact with them and put my hand up in a questioning'wtf are you doing?' way, but these idiots don't seem to care and only think of themselves.

They should be on the other side of the road.

If the shop or whatever you're going to is on the opposite side of the road, you bike on the good side and then cross the road to to the place you need to be. Don't be a lazy and inconsiderate prick.
