2 cases I've experienced yesterday gave me that idea.
First one was early in the morning at about 8 at clementi. I was in Bus 52 when I saw this car, from the extreme right lane, which is a right turn only lane, cut into the middle lane. He was horned because he changed lane so suddenly, and risked being hit by a big lorry. Not only that, he didn't signal. To make things worse, he stopped at where he was, waiting to change into the extreme left lane, making the big lorr ydriver horn him again. And this time, he wasn't signalling again.
The next thing I know, he drove past the bus I was in, wound down his window, and pointed the middle finger at the lorry driver, who horned him twice.
I mean, dude, you're in the wrong. Firstly, signal. Secondly, even if you signalled, it doesn't mean that you can cut in front of a vehicle just like that. He will have to brake suddenly, and horn you definitely. Lastly, why stop in the middle of the lane while trying to change to the extreme left lane? The next left turn is 2 traffic lights away, and you could easily overtake the bus I was in, before changing to the left lane.
You even drove a luxury car, wore a suit, but too bad you're a bloody old man with no manners and driving etiquette.
The second incident was when I took Bus 852 home from my workplace. I think the bus driver thought that he was driving in a Formula One race. He braked so abruptly each time to either stop at the traffic light or at a bus stop, and then he accelerated so quickly too. The worst thing is that the bus is full of people, and everybody was struggling to stand properly, even if they were holding the seat handles.
And the bus tyres even screeched when he made a turn. It's either he drove really quickly, or that he drove so recklessly until the bus is spoiled.
And who said Singaporean drivers are good, polite drivers? Geez.
