Yeah, they swerve left and right in between lanes like their father's road, and even family man with one boy and wife also do that sometimes. Can they get a life?
And to add to that they come out of T-junction without looking. they assume we will look out for them.

One way to annoy them is to speed up during rain beside them because they will kena the puddle splash.
And also one more way is to simply put your wiper on max speed and press the water spray. I do this especially during traffic jam, when i see moto coming along my side, I quicky press the front screen water spray and put the wiper to max. They always kena one. sometimes their reaction very funny like they look behind and give cock stare or soemtimes try to swerve after they kena the water. LOL
