Most of them ride like they're above every vehicle on the road, like before a car/truck/van want to change lane or enter another junction, they must first let those bikers pass first. And those bikers mostly they don't care if you turned on your signal, they all assume that you the one should let them pass first instead of them slowing down and let you go.

And to be fair, if you saw someone turned on their signal you can choose to slow down and let them pass right?

Don't be one of those please.

About that 90km/h, mentally stable person would definitely wait for the 5 ton lorry to pass then change lane right?

People talking about bike you talking about high speed lorry.

Not about the size or vehicle la wei, people give signal and if you seen it from KM away, can you slow down and they them pass or no? If stupid give signal then immediately turn that’s different, this is you give signal early on and if the biker being rational they can just slow down.
