Vehicles going straight always have right of way.
Wah I dont wanna teach you how to drive.
But usually, you inch in, you can tell if the guy slows down or is an asshole by speeding up anot.
So basically, you just inch in to "test water".
The fella will know your intention already.
If can go, just go.
Worst thing to do is to hesitate.
Speeding up is the best way to lane-change.
You dont slow down the cars behind.
Picture yourself pushing a trolley in a supermarket.
And you will understand.
Driving is very similar.
You will still check blind-spot corners when pushing a trolley.
If you have balls, sinkies will usually give way. (Inside their car kan you anot is another story)
When you see a trolley coming very fast, you also stop and mumble "siao" to yourself.
If inch in , u move forward, accident whose liability? 50/50?
